One thing about Haechan, he never forgets to burn the studio with his talent and passion in music. He knows very well his abilities and disadvantages then always strike to improve intensely in every single comeback. When you look at him closely, there are so much thing to be proud of abt him. He grows up so well as an artist. He excels in vocals, dance, variety shows, stage presence, and always presents his trademark and fresh flavor in each of his artworks. Most anticipated member to do solo in the future, nct's ace and all rounder haechan, you did very well! Thank you so much!

When Haechan said he's SM future, he's not kidding.

Haechan's about to lose his voice and yet delivered that high note perfectly

I've heard Haechan's voice a million times now but I still never get tired of it it's just so Beautiful

Haechan, Renjun and Chenle's vocals makes me crazy. Imagine how many times Haechan belted out notes, my throat hurts for him. Let's all agree that this video makes it for us to sleep tonight 🙂

haechan recorded so hard. he's getting better and better. haechan tried so hard when he was already losing his voice. haechan you did your best and you came out with the best results. we're happy and proud for you

i mean.. Haechan's voice is literally amazing and he's literally doing really well.

0:45 2:50 3:43 5:27 8:27 10:04 11:28 don't mind me, just saving time stamps for honey voice 🍯

Y’all don’t understand how good Haechan is like he REALLT doesn’t get enough praise for not only upholding his unique tone but being able to show variety with high notes these high notes compared to hot sauce are less airy and just stronger and he aced them even tho he felt sick - don’t leave no backhanded compliments just say he did good and move on wtf

Remember when Jaemin mentioned that they could see Haechan's passion for singing even more during Hello Future recording, and boy didn't lie 🙌🏼 our Haechannie's high notes are to die for!

Dangggggg Haechan did the high note so well! I could imagine the headache he felt when he used his head tone. I almost thought he strained his vocal chords, good thing we were able to hear him speak softly after recording

Haechan, Chenle, Renjun and Jisung’s vocals are heavenly. I could listen to them sing all day. Jeno, Mark and Jaemin’s rap goes so well with the vocalists. ❤️❤️❤️

HAECHAN's vocal range is crazy and the most impressive thing about him is that he’s always improving himself his vocal potential is limitless so if he’s this good at the age of 21 i can’t even imagine what’s waiting for us in the future

Haechan puts his everything into this like I don’t think y’all understand just how amazing he is, how beautiful his voice is, and how hard-working this guy is and others can see it like?? I love him so much

Lee Donghyuck’s vocals!! Omg he never fails us.

I love how every comment is about Haechan. Every time he appears on screen on a MV I know my ears and senses are going to travel to another dimension

There are tons of words that could describe how remarkable as a singer Haechan is. Neither of them are enough to fully describe his talent and passion in his craft. The phrase; Haechan is a great singer, would still pass as an understatement.

NO ONE is really touching haechan. Haechan is in a league of his own in his generation. I'm beyond proud of him. 💛

Kenzie always pushes Haechan on how high he can go with his pitch but it always comes out beautifully. She's one of my favorite producers (as a long-time SMTOWN stan) and she knows what he's capable of. Hope he had some tea with honey after those sessions though hahaha 😅

I can't express how happy i'm to see people recognizing and admiring Haechan's voice and talent. Not only he's my bias in NCT but he's simply the LOVE of my life

Haechan NCT해찬 is more than a FUNNY guy, he has a lot of talent that is why they are calling him ACE He is SO smart in everything even the members prove it, and don't be hypocrite all the youtube content you can see him leading them because the member's trust him on that part. He is in 3 units and that says a lot it means SM knows that haechan is truly a gem!

I’ve been waiting for this! It’s not easy to perfect the pitch in recording sessions, so I like how they show us how to get there. Haechan did so well! The vocal stamina needed to reach those high notes AND record the rest of the song is no joke. I looove Hello Future and all their hard work has really paid off.

hyuck was losing his voice and he still nailed the high note what an ace

이거 볼 때마다 뭔가 조금 씁쓸하면서 슬픈 게 이해찬 고음파트 거의 다 혼자 맡고 있어서 목 갈라 그러는 게 마음 아픔 127 활동도 그렇고 그냥 거의 두그룹 활동이니... 쉬면서 했으면 좋겠다는 생각이 정말 오만개 들었어 0_0... 건강해라 이동혁...

The comment section is full of Haechan lol, and I will too. Out of all NCT members, his vocal color is my absolute favorite (not saying others aren't amazing cuz they are). Even before I was a fan, his voice stood out to me when I listened to NCT songs. Now as a fan, I can't get enough, I want a Haechan solo song or album so badly, I could listen to him for hours. If he did something acoustic that would end me haha

haechans face listening back you can just tell he KNOWS he’s that bitch. i love a singer who knows they can sing and isn’t afraid to show it

i cant believe how amazing haechan is he was already losing his voice and still sounded like THAT hes just so amazing aggghh

Honestly Haechan and Chenle have such an insane range! It's really amazing

Imagine being one of the funniest members but also the most reliable and all rounders out of the WHOLE group. Haechan is one of the best dancer, one of the best vocalist, one of the most charismatic members. Members in NCT are already hand picked perfection but imagine being amongst the best within that group. Wow.

I wanna cry seeing haechan. He really did great and perfect. He put his everything into this and he nailed it. I'm so proud of you, haechan and other members too. But i'm more overwhelmed seeing haechan hit the perfect note until he got sore throat plus he's too busy :'((( i hope he's doing well and stay healthy.

I have nothing but respect for Haechan and the rest of NCT Dream! Hello Future is so different from their usual stuff but it was so amazing and really cool to see different sides of each member. Definitely one of their best songs in my opinion

haechan, you've been working hard all this time. thank you for your efforts for nctzen by giving such a beautiful voice. you are so great. Haechan and the rest of NCT Dream have worked really hard, thank you so much!

Haechan: so how many high notes am I doing in this one? SM: how many Nct members do we have?

Haechan has once again proven that his vocals are TOP TIER, but I’m concerned for his throat. I hope he isn’t overdoing it, and that he’s taking good care of his voice.

Renjun's voice is amazing😍😍 he's so talented

Vocal line- really killing it 😭 renjun doesn't get enough credit for his vocals

Only Haechan can do what Haechan can do. Haechan is IRREPLACEABLE. And that marks a real main vocal.

mark and haechan's studio recordings always sound exactly the same as when they're rapping and singing live, they're insanely talented

Haechan almost having a breakdown at the end made me cry tbh

And here I am adoring Haechan's voice whenever it is his turn. His voice is just so soothing to my ears😍🥰

as expexted, haechan is truly an ace, he's 21 years old, and he can sing very very well, i just love the way he hits every highnote.. and ofc, im very proud of each and every one of them, really. they work really hard for this song, and hello future really turns out to be a masterpiece

Donghyuck is not called “main vocalist” for nothing! You did great haechan!! I love you always 🥺💚 always proud of you!

HAECHAN VOCAL IS INSANE, AMAZING, I'M SPEECHLESS,WOW, OMG, OH MY LORD, WOW

i love this comment section sooo muchh....i just wanna stay here and feel all the love you've given to Hyuckie😭😭he is so precious

Hello future behind the scenes recording again proves my point that HAECHAN has the most versatile and top tier vocals in the entire music industry and not just kpop.

missing "Hot Sauce" & "Hello Future" era already !!!! :')

The comment section is full of Haechan so I will praise the other members first. It was so impressive to see how Chenle, Jaemin & Jeno provided the backing vocals on the chorus, it gives the song so much texture. Chenles voice is so beautiful, definitely one of my favorites. My bias, Renjun .. omg his voice is stunning. Him singing the high part in the chorus was everything. Jeno's rapping tone gives goosebumps. It's so powerful. Ugh Jaemin .. I adore him. His rapping tone has such a rich texture that adds to the songs versatility. Mark is the moment. I love when he adds rasp to his rapping, his cadence is amazing. One of my FAVORITE rappers (top 3 for sure). Jisungie has such a stunning singing voice. He brings a softness to the song that's needed. But his rapping tone 😩 POWERFUL. Now to Haechan .. I need him to stop lol. That boy brought me close to tears with his high notes. He puts his entire soul into his singing. Magnificent voice. Stan NCT Dream or you're missing out.

You can tell Haechan wasn’t felling well and was struggling a lot. But he didn’t complain or say “let me just do it a lazy way” or ask to come back another day. He worked through it like a real professional

True fact: Renjun high notes are not joke. His high notes is perfect.

the title should be: *NCT DREAM DOES’NT KNOW HOW THEIR VOCALS MADE FANS CAN’T GO TO SLEEP*

The way Haechan hit the note. aaaahhhhh I'm speechless he's already out of the world so proud of him. This boys always breaks nctzen's expectation like OMG! okay I'm gonna stop right here i'm gonna cry na lol! btw i really want Haechan solo asap maygaaaaad SM what are you waiting for!?:) o_O

해찬아 팬들이 너의 노력을 알아주니 지칠때 좋은 말 많이 보고 만약 코로나때문에 목에 무리가 가서 옛날처럼 목이 안 나와도 슬퍼하지 않았으면 좋겠어 넌 언제나 더 열심히 하고 노력하는거 팬들은 아니까! 헬퓨에 목소리를 갈아 넣은 애기야 수고했어!! 드림이들아 이 노래 너무 좋다ㅠㅠㅠ 레전드 활동곡을 함께해서 너무 좋아ㅏㅏㅏ

HAECHAN so reliable and consistent like u can give him literally any high note, any song and he'll execute it perfectly no matter how hard it is

Renjun: The song is too high Also Renjun: * hits the notes *

Haechan you did it soo soo greatttt! I love youuuuu

Renjun said "the song is too high" but they effortlessly reached that 😌

but chenle and jeno are actually SO stable. it amazes me every time. and haechan, my gosh, every time he steps inside a recording room he chooses violence lol it's amazing because you can literally see his passion burning~ NCT Dream is really one of the best groups out there, with many different tones and every single one of them is SO GREAT.

It makes me so upset that SM has an AMAZING main vocalist like Haechan but they don’t promote him better. It’s unreal. nctzens should appreciate him more too. He’s truly incredible

"my throat feels like it's about to lose my voice" i actually started getting worried about Haechan - his talent and skills like damn dude you're doing so much

i really addicted with haechan voice!!!

all i can say is HAECHAN'S THROAT DESERVES A PRAISE

Haechan is only 21 years old but he's already this good?! Imagine how powerful he is as a singer in the future... Insane !!!

얘네 메인보컬들은 진짜 감탄밖에 안 나온다.. 너무기특해요..

Donghyuck fullsun look soooo satisfied with his voice, that confidence tho🌞 lots of love for all the members also. Nct Dream fighting!!!

now imagine if HAECHAN has a solo.. he would definitely eat up everyone

oh my fucking god Haechan literally left me in tears, he's unbelievably good wtf this boy deserves the world

해찬 미쳤다~ …..음색+가창력 다 갖춤

해찬이 넘 고생했네 진짜 ㅜㅜㅜㅜㅜ기특하고 안쓰러운 마음

this. the special tone of Jeno's voice, the addictive flow of Mork's voice, the vast range of Haechan's voice, the beautiful melody that Chenle easily makes, the heavenly perfect sound everytime Renjun sings, the deep deeper and dark cool Jaemin voice is, and the distinctive heavy voice the cute maknae Jisung has. it all always combines perfectly and complement each other very well.

haechan rlly gave his 100% for this song you can see how exhausted he was in the end, I admire him so much!! He did rlly well in all of his parts!!

I want to cry seeing haechan, he is the one with the highest tone, and yes thank you very much for haechan and dreams for working hard for sijeunii thank you again

I came to watch Haechan's magic in the booth.😍🤩Just from listening to this amazing track I knew he put in that werk😭👏👏👏

this is random but i really like the way they recorded this behind the scenes cut compared to their other un-cut videos. they show the members recording their parts in the order they progress through the song, rather than showing all of one members lines and then another members lines etc. it feels easier to see the bigger picture of how the song is pieced together

Jaemin once said that Haechan's throat almost bleed while recording the song . We are proud of you uri sunshine we will always support you heachannie will he get rest though 127 albums are also coming up..

해찬이가 찢었다!! 🔥🤟🤟🔥 SM이 레코딩영상을 계속 푸는 이유 = NCT 실력에 대한 자신감

SM really is the house of power vocals. No one can ever comes close.

renjun: the song is too high also renjun: *does it smoothly anyway*

Haechan is 21... Already has soloist potential. Can't imagine what his skills would be by like some 5 years. Oof!!

Oh how I just love Renjun's soft voice, so delicate, so sweet, so refreshing.

haechan’s voice is actually insane

Haechan belting out those highnotes and then ending and whispering “thank you” and looking like he’s gonna pass out from it i- he really went all out for Hello Future!! Not only that, Jaemin said “now I know why Haechan came out with a hoarse voice” 😳😳 Haechan rlly has a crazy vocal range

I like this version of recording behind the scenes wherein they showed us how the dreamies pull off every line or adlibs in the song. Also wtf HAECHAN, I feel like his throat is kinda sore bcus it might happen during the hot sauce era or he also have a recordings for 127 comeback.

Damn, Haechan can really pull a belted note off. Now I know why they usually use AR instead of singing 100% live, he wouldn’t be able to pull of that big ass high note while dancing.

Why is Haechan's part so addicting ❤️❤️

HAECHAN is a kind of person who’s striving for flawlessness and always setting excessively high performance standards. just look at how he tried doing his best recording hello future with pure and raw vocals, he’s indeed born a superstar!

being a sunflower is constantly being amazed and proud of haechan because he's perfect in everything he does and always gives his 100% never slacking even for a little bit

i wanna give all the dreamies a hug, specially hyuckie he did so well with all that highnotes! ilysm dream

Jeno's rapping skill really improved a lot in 2021. He has found his style and sound.

One of SM’s best decisions to flex their live vocals through these behind the scenes recording videos, as they should !!

I'm not breathing when Haechan starts singing high notes. proud of haechan

몇번을 봐도 이해찬 진심 미쳤어 ..

noones doing it like haechan hes just such a great vocalist

#haechan is a kind of person who’s striving for flawlessness and always setting excessively high performance standards. just look at how he tried doing his best recording hello future with pure and raw vocals, he’s indeed born a superstar!

HAECHAN said "my throat feels like it's about to lose my voice." he literally did a lot of high notes but he nailed it anyway. HAECHAN ACE

Haechan isn't my bias (it's Renjun) but his singing skills are really out of this world! From the lowest to the highest notes in seconds. He's one of the best singers I've seen so far in the K-pop industry! As the comment below - Haechan is too much underrated!!!

All dreamies did their best on this work, but the fact that haechan takes the important n amazing part for this is undenial, haechan is real the ace.

Haechan : My throat feels like it's about to lose my voice. also Haechan : *hits high notes like its nothing*

to think that heachan has a hoarse throat and still killed his parts. never question his lines, he's a literal ace with an amazing vocals and dancing skills.

people might see haechan a very happy sunshine , a bright person but if its performance already he gave his 101% example when they do a reaction to their mv he really check himself performance if he is doing really well and i wish someone say to him how precious he is. I really love him

해찬아 목소리 진짜 좋다.... 너무 좋다 엔씨젠이 된거 후회안해😭😭👍🏻👍🏻
