the vocalist you liked is Donghun and the crop top guy is Byeongkwan

"What is this outfit?!? Oh my god, I love it" That was my exact reaction. Byeongkwan is really shining in this comeback

*byeongkwan with those pigtails is iconic*

The rock song I've been begging for forever

I love Ace. They're so so underrated it's a crime. Thank you for reacting to them PD

A.C.E is so underrated and i hate it, i hope they get more recognition form now on :(

The guy with the pigtails is named Kim Byeongkwan. The brown-haired vocalist that you liked is named Donghun. The other rapper, with the silver-ish hair is called Wow (yes, Wow). The red-haired is Chan (former UNB member), and the black-haired is Jun, the leader of A.C.E.

I’ve been dying for a good K-Rock song from a K-Pop group. Loved this comeback so much.

i unintentionally yelled YES when i saw that you uploaded this KSJDJHF OOPS

The member with the crop top: Byeongkwan The member with the voice you liked: Donghun And no, they haven’t done this style before! The b-sides from the album are really good too, it even has the song that was meant to be their debut song (Do it Like Me)! I highly recommend it 💕

OMG I'VE WAITED FOR YOUR REACTION FOR SO LONG, THANK YOU

Finally !!! I waited for this reaction so long 😆

PD: The members were really reaching out to me Me: Jun could sing me off a bridge.

Th guy you like at 4:10 is Donghun Also, yellow crop top guy with pigtails is Byeongkwan.

"Oh my god he like.. GREW UP!" i love his reaction hahaha

You probably have no idea how happy i am right now:’)

one of my most anticipated kulture studies!!! thank you pd!

I am so Happy so see sooo many Choice waiting for reaction to A.C.E videos 🤗❤️🤩

The one in the crazy outfit with the killer rap lines is Kim Byeongkwan! ;) Also this music video and the song hit me hard.. I think it's been quite a while since I've been surprised and blown away by a comback that much! But that's the cool thing about A.C.E: You'll never know what you get the next comeback, but whatever it is: They slay it!

*I SUGGEST A.C.E 1ST WIN BECAUSE WE CAN'T IGNORE THE FACT THAT THIS SONG IS A WHOLE BOP*

You have no clue how I much I waited for your reaction!!! And now you gotta listen to Oneus's Twilight!!! 😃😃💕

Omf thank you for reacting to this!!

As for the music video, I like the text graphics a lot too and I like how they refer to A.C.E's previous releases. I mean idk if all of them do but some do.

I was cleeeearly waiting for that reaction! I’ve love ACE since their debut but boooiiiii that song is just awesome! Please stan 😇

OMG I WAS WAITING FOR YOUR REACTION 😭💜 thank you so much ... A.C.E will definitely gain more recognition with this comeback! 🔥 THEY WILL BE BIG 🙌🏼

YES IVE BEEN WATING FOR THIS AHSHHSJS DNDHD

I listen to a lot of kpop songs and ace undercover is for me one of the best of 2019

I clenched my butt cheeks so hard in excitement when i saw this in my recommendations *I DONT KNOW WHY I GOT NO NOTIFICATION CAUSE I CLICKED THE BELL DAMNIT* this has been my favourite comeback of 2019 so far

It doesn’t take you to another level it takes you higher

I clicked so fast asdsgljsj;. Thank you for the video, it is indeed an amazing comeback! They never tried this style in their own songs before, and by the punching energy, I think, only the ultimate emo song Cactus can compete with Under Cover. But while it is something new musically, A.C.E is really powerful group in many aspects, so I see Under Cover as something that allowed them to release that energy A.C.E always had. The song goes even harder with the choreo!

So glad you had the opportunity to react! I love this song.

"I'm sorry it took me so long" U DAMN RIGHT

I love A.C.E. As they fully live up to their name they are totally out in dancing, choreo, singing, visuals. As I said everytime you watch and hear the video you find easter eggs. Thank you for reacting and Im glad you loved it.

Thank you for reacting !!! I've loved ACE since Cactus came out and I've been waiting for people to jump on board because they have always been amazing. ❤ They are perfectionists when it comes to their performances and they work so hard. I saw their live show in Dallas last year and they were UNBELIEVABLE. ❤

FINALLY i loved your reaction just as much as the actual song. now i can die in peace lmao

I'm glad you like the song and mv! Thank you for reacting to it!!

Thank you so much for Reacting to A.C.E! I personally love how they never seem to hold back every comeback no matter what - plus the scene when Jun (the one with the blindfold) just jumps in with soft vocals after the rap was awesome! The one whose Vocals you like is Donghun (and yes he got an eyebrow piercing for this comeback), and the rapper in the croptop is Byeongkwan! If you like old school kpop then their b-side on this album called Mr. Bass realllllyyyy reminds me personally of SHINee. Thanks again for reacting, and I hope you have a lovely day!

You should make a listening party for their album! It's really something 💕💕💕 Please??💕💕

That video was a journey, holy shit. And I didn’t know Byeongkwan was in this group. I loved him in Mixnine, he was always so consistently good. Definitely gonna support this comeback

I am so happy for A.C.E and this comeback showed a lot of people just how talented they are. STAN TALENT STAN A.C.E

This kind of music style hasn't been done by A.C.E so yeah this was new to us too... This killed us as well...

FINALLY DUDE. I WAS WAITING FOR THIS. THANK YOU!

Omg thank you so much for your reaction! IT IS DOPE YES THEY KILLED IT IN EVERY WAY THANK YOU MAN

FINALLY I HAVE BEEN CRAVING FOR THIS THANK YOU PD!!!

thank you so much for doing a vid on A.C.E's Under Cover, your analysis(es?? lol) are always spot on 😭😭

Yes finally this is the reaction that i really waited for👍 My excitement for their comeback was like the rock guitar in the song haha. They deserves more views and we can't sleep on them!!!!

Thx for reaction 🤩❤️😍

Thank you for reacting to A.C.E and THANK YOU FOR RECOGNIZING THEIR VOCALS! I feel like so many people are so blown away by A.C.E's choreo and visuals that their vocals always get overlooked, and I'm so glad someone noticed them this comeback!

Choices are in the house!!! Thanks for your analysis/ reaction PD. I always look forward to seeing your analysis/reaction s. I got to see them live in Dallas this past December. They are more amazing in person if you can imagine that got to High Touch too.

Aaahh I was waiting for this for so long!!! Never clicked so fast omg

they're doing well on the charts too and that makes me happy

Bless🙌 thank you for this reaction, I've been waiting forever😍😭

A.C.E just keeps getting bettwr with every comeback. From Cactus to Undercover you can really see how versatile the whole group is. And even though they change their aesthetic from time to time you can clearly say it's an A.C.E song. I really look forward to to seeing them grow continuously and try out new styles! Thank you for reacting to this PD!

Glad you liked it! The dude with the "pigtails" you liked is byeongkwan

the guy who's vocals and performance in the video you were talking about at 4:17 his name is donghun!

I really appreciate your opinion on videos and music in general, so I'm very happy that you reacted to them. Also, I find it quite pleasing that more and more people realize A.C.E are different, to me they feel like a "statement" that shouldn't be overlooked!

This song brought the energy that they had during their tour and I was THRIVING THEN and THRIVING NOW.

YESSSS THANK YOU FOR REACTING TO A.C.E

Under cover is probably my favorite kpop song to this day, and i dont think that's changing. Also beongkwan in those crop top outfits has me gone, shook, baffled, wrecked, and so on 😳 he really shines in this comeback

YEEEEES I HAVE BEEN WAITING.CHOICES, LETS GATHER FOR THE BEST REVIEW

I was waiting so bad for this reaction! Your comments are always so good 💝💝💝 love u

FINALLY!! THANK YOU!!! And thank you again for putting Sehyoon in the thumbnail😂

they re so underrated its just unbelievable.

Byeongkwan with his fashion and vocal tone....he became my bias. All their B sides on this album are amazing!!

i'm waiting for you to react to this song so bad...they are good tbh...vocal, outfit, rap, visual everything was on point

hearing you be so lyrical about a.c.e makes me so incredibly happy! as a fan i already had high expectations but they completely blew me away with under cover!

yass!! finally!! thank you for reacting to ace

Is 2019 going to be a rock-genre year of kpop? WE STAN.

I really recommend checking out their b-sides for this album. It's really good!

Oh my gosh thank you so much for reacting to this!! So glad you enjoyed it. Please give A.C.E lots of support and love!! They really really really deserve it 😫

can you believe it i rewatch this video again? i love people showing love to A.C.E

Who agree with me that this UNDERCOVER currently the best song of the year 2019

I love this comeback so much, it got into a.c.e more than ever. Before I casually listened to them but now I love them so much, they're incredible

OMG!! FINALLY!! You should react to their new album songs❤️🥰

I yelled when I saw this notification. Thank you so much for reacting to A.C.E. I'm a Choice a.k.a aprlart of their fandom. The guy that you liked who was singing is Donghun and the one with the pigtail is Byeongkwan. Also top of the crop and pigtails one of them also had glitter eyebrows.

I DONT KNOW HOW MUCH IT HAS BEEN for a song to headbang to EVERY TIME I HEAR !!! That heavy kpop band vibe… love it !! Wish they keep this up

IVE BEEN WAITIN FOR YOU TO REACT TO A.C.E AGAIN PD

A.C.E is one of the most hardworking groups. You should watch their BUSKING video

I have been waiting your reaction from the first day A.C.E drop the EP, i really want to hear what the professional thought about the EP, thank you so much for your time to take look their EP 😄 it was an honor for me

yes thank you i have been waiting for this :)))

IM SO HAPPY DJDKJDKSJKSKS I SCREAMED DURING CLASS WHEN I SAW THE NOTIFICATION

AHAHSJSKSKSK IVE BEEN WAITING FOR THIS

When PD listens to the people... We do not disappoint. 😉 Thank you for reacting to this!

I literally just woke up and had to calm my ass down bc i was bodyrolling and screeching to ur reaction. i legit wish i was lying lmfaooo

this video arrived at the right time

Your reaction to this song was just amazing. Since your Cactus and Callin reaction, i've learned more about the songs finer points because of reactors like you. I hope A.C.E get more recognition this time. They also just placed #9 on Billboard's World Chart with this song alongside big name groups!

YESSSS I've been waiting for you to do a video about Under Cover :')

OMG YASSSS YOU FINALLY REACTED!!!!! A.C.E’s comeback is soooooo good

Thank you so much for reacting to a.c.e again! I loved your reaction and insight on the music video! I actually didn’t really consciously noticed the colour desaturation but now it makes me appreciate the mv and that transition even more!

i nerded out so much watching this, you really hit all the spots with your analysis!!! i just came here for a.c.e but i think i def wanna see more of these type of analytic reviews of kpop videos rather than ur typical reaction vid, i'm so hyped right now and feel super proud to be a choice

As a Choice, in their past albums, they don’t have any side tracks that sound like this. This was a risk, BUT IT WORKED. The sound, the visuals, everything. 10/10 one of my favorite songs now. It was AMAZING. The member in the crop top is Byeongkwan. He’s my bias wrecker! 🥰

Ah, so I got in to A.C.E. from this song. Had briefly heard some of their other songs, and at first like certain aspects of this song when it came out 2 weeks ago. Recently it grew on me, and I am legit listening to this song multiple times a day. I went to check out their funny videos on their channel, and holy cow I REALLY like them. The performance of this song gives me chills. The dance is SO good. Their vocals are SO good. And they seem really genuinely close. And their company seems cool as hell. I stan.

I HOPE THEY BLOW UP CAUSE THEY DESERVE EVERYTHING AND MORE

AHHHH FINALLY IVE BEEN WAIITNG FOR THIS THANK YOU!!! ♡

Ahh thank you so much for reacting this! Was very excited when I got home and saw the notification. I’ve loved ACE since debut but this is definitely my favourite song of them so far! If you feel like checking out the rest of the album in your free time, I recommend Mr Bass- it’s so fun! And this is the first time they’ve done a rock thing btw.

THANK YOU FOR REACTION OF UNDER COVER!!! I recommend you check out their discography, they have a few songs but they all have their own style, quite diverse, they love experimenting with songs and fashion too

Love ACE, especially Donghun's voice -

I really love this song!!! I love the rock feel of it! I can’t stop listening to it!

thank you for reacting to A.C.E ^^ they are so underrated people need to stop sleeping on them and music shows need to stop cutting their songs anyways Stan Talent Stan A.C.E ^^

Thank you for this reaction video! its really interesting to get more insight on production techniques from a professional!! ❤❤😯😯
