This was AWESOME!!! What did you think about this collab?! :D

This was without a doubt the most seamless and cohesive collab I’ve ever listened to. They didn’t sound like a collab at all they just sounded like they’ve been together forever. Can’t give it enough praise. ❤

Thanks for the reaction. I am the BESTY (fan name) of BE:FIRST fans. Their voices were so well matched that they looked like a group of 15! BE:FIRST is a group that specializes in live performances, always singing live with hand microphones. Please check out their official channel for music videos, dance practice videos, and live videos.

Ateez and BE:FIRST energy match so well… THAT DANCE BREAK?! I need more of this collab

Hi I'm besty(BE:FIRST fan) and almost Atiny, Please react to another BE:FIRST 's stuff Masterpaln ,Mainstream,Milli Billi, Scream BTW Ryoki is close friend of Yuta (NCT127).

I was waiting for your reaction!!!! I'm a hard core ATINY and I didn't know about Befirst, they blew me away! They are all rounder multitalented kids with amazing vocals and dance skills! This is really THE COLLABORATION OF THE YEAR!! I don't think I have ever heard of this type of collaboration from 2 different countries and different agencies... The scale of this is AVANT-GARDE and Guinness record. The MV has so much to unpack. Very creative. Mindblowing collab!!!

I'm an Atiny. On first listen, the chorus absolutely grabbed me, but I had to sit with the rest of the song for a couple of listens to have it gel in my head. It's funny you mentioned NCT because I have to do that with a lot of NCT experimental tracks, too, so it definitely had that vibe for me. I really like it and it did make me start checking out Be:First music. As I said in another reaction vid, the production on this is so interesting to me for exactly th reasons you mentioned - it's unusual to have full group collabs, and they really did merge the Korean and Japanese production teams for this collab. I cannot recall ever seeing such a complete full group collab in kpop previously - usually I've seen partial groups, or one team is mainly in charge of the production, or they bring in outside producers for the project. This was really unusual, and I hope we see more collabs like this.

リアクション、興味深かったです。 このコラボレーションは素晴らしい化学反応を巻き起こしたと思います。 もしよければBE:FIRSTの曲もリアクションお願いします。 Masterplan BOOM BOOM BACK Masterplan 彼らはライブで最高のパフォーマンスをします。

Thank you for your reaction💕 The first person to say ”BE:FIRST “is Sota.Sota’s dance is crazy. Sota has won the world dance competition four times. The collaboration between BE: FIRST and ATEEZ is amazing. This collaboration started when ATEEZ appeared at "D.U.N.K.Showcase n KYOCERA DOME OSAKA" by SKY-HI, the CEO of the company :BMSG that BE:FIRST is belong . So Mingi and Hongoong performed rap collaboration songs with other groups ‘s rappers (including SKY-HI of CEO and rappers ,and BE:FIRST's Ryouki). I went to that live show, and it was so cool. It has been a long-standing dream of SKY-HI to interact like this beyond the boundaries of the group. I think it is might borders and genre barriers that ATEEZ is breaking in the video of this MV. " We don't need shields and spears. “ I guessed as if he was saying, "Just enjoy the music." K-pop and J-pop are also losing barriers, so SKY-HI used to say that if he dare to classify it, he ‘ll call it A (Asian)-pop . You can watch D.U.N.K.'s rap collaboration video on the D.U.N.K. channel.↓ “#7 (D.U.N.K.) SKY-HI Rap collaboration” You can also watch a part of ATEEZ's live performance and other groups‘s collaborations on the D.U.N.K. channel. Please check Masterplan,Mainstream of BE:FIRST,too. From Japan ❤️🇯🇵

They paired members together so PERFECTLY! The best collab I have heard. Equal exposure and both came out looking absolute fire.

They have been invited to rock festivals since shortly after their debut, each time with solid and positive results. Now they have become a regular at rock festivals despite the fact that they are a dance and boy group, and they are trying to become a one and only boy group, having acquired the "ability to convey music", which is the soul of rock, to the point that they are recognized by rock fans. Their live performances are overwhelming and phenomenal.I hope you will watch and react to it.Subscribed to channel!

Great reaction. It’s been said and I agree that Ateez and Be First are so evenly matched that they could almost be the same group. Ateez management, Hong Joong and Mingi wrote the lyrics for the song. It’s like they wrote it specifically for Be First. Fun fact: Sota (the opening Be First member) was a backup dancer for Ateez at K-Con Japan in 2019.

I am absolutely obsessed with this song, it’s a flawless collab, and a true collab too, which is rare. So good to see them actually working together.

素敵なリアクションありがとうございます。そしてBE:FIRSTに興味を持ってくださってありがとうございます😊 この夏ATEEZとBE:FIRSTが一緒に出演するフェスがいくつかあるのでパフォーマンスとして披露されるかもしれません NCTが好きと言うことですがユウタくんとBE:FIRSTリョウキは仲良しで ジョンウはBE:FIRSTソウタのダンスに魅了されてソウタくんのことが好きみたいですよ

リアクションありがとうございます😊 このコラボは素晴らしいです。 ATEEZはとても有名ですが、BE FIRSTは日本では有名ですが、世界ではあまり知られてません。 是非他の曲も聞いてください。 私のお勧めはmainstreamです。 これはほとんど実写のすばらしい作品で日本では高い評価があります。

リアクションありがとうございました😊❤ sky-hi (BMSG)のオーディション「THE FIRST」から2021年にデビューしたのが、BE:FIRSTです😊　デビュー曲のGifted オーケストラバージョンも是非観てもらえると嬉しいです☺️ Thank you for the reaction of BE:FIRST & ATEEZ♪ I hope you will continue to enjoy ATEEZ & BE:FIRST's music together❤😊

細かいところまでリアクションしてくれて嬉しいです！ BE:FIRSTとATEEZはSKY-HIが企画したDUNKというフェスで共演してから 今回のコラボが実現しました BE:FIRSTの他の楽曲のリアクションも是非お願いします！ ありがとうございました😊

Thanks for reacting! 🇯🇵 I really hope you guys to react more BE:FIRST music. The latest release is called masterplan. Mainstream is also fire!

リアクションありがとうございました 作曲のほうにはbe firstのメンバーであるMANATOが参加してます 深いところがわかってとても嬉しかったです be firstの『masterplan』『main stream』を聴いてみてほしいです

Thank you for reaction, from JAPAN🇯🇵 Your reactions were fun because they were full of beautiful music love like this song!❤ I would love to hear your reaction to BE:FIRST "Mainstream" as well😊

Thanks for preparing for BE:FIRST. This collaboration was possible because of the trust between ATEEZ & BE:FIRST.

Im addicted to "hush-hush"

Hongjoong and Jongho sound like each other when singing, so it's not surprising that if one of BE:FIRST's members sound like one of them, they'd sound like the other one too.

This is BESTY. Thank you for your reaction. I'm glad you looked into it. ATEEZ is so powerful that I became a fan. BE:FIRST has a strong voice and dance, and is non-genre, so I think you will enjoy it. I hope you will listen to their other songs as well.

I'm an Atiny and i like this song so much. Be:FIRST are really good and them and Ateez are amazing together 😊

Thank you for the reactions! I am the fandom BESTY of BE:FIRST. About RYOKI, who you mentioned at the beginning, he was in the same film as NCT's Yuta and we are good friends in Private. By all means, if you like NCT, please react to the other songs of BE:FIRST, I think you will like them!

If you guys haven’t already. And enjoyed this collab You need to check out their works , Mainstream- BE:FIRST!!!

リアクションありがとうございました

Thank you for your reaction ♡ Both are very nice! and I liked your reactions too. Keep an eye out for BE:FIRST! and listen to the other songs ♡ I guarantee you'll enjoy them!😊💖

Thank you very much for your reaction. Happy to check BE:FIRST in advance. Many of BESTY (BE:FIRST's Fan) mentioned about BE:FIRST in the comments. They are just 3 year old from Debut and quite similar background with ATEEZ. Both are debut from start-up entertainment management company, like JPY. HYBE, the same for BE:FIRST. SKY-HI, executive producer of this music is very famous rapper and CEO of the BMSG, developed in 5 years ago. So, the verse Shunto rapped "underdog" .ATEEZ is absolutely global artists with 6 year oversees career and BE:FIRST is just about to go for it. But BE:FIRST are making great success in Japan, representative, J-POP Boys Band.. SOTA gripping the train is a rapper and lead dancer, who won HipHop International dance competition for 4 times. Both group has the same views to be topper of the music scene being themselves, being unique (no one like them), and go beyond stereotype stuff, breaking through by their abilities. Please check their Mainstream and Masterplan. Masterplan is quite dope Japanese drill hiphop tune.

素敵なリアクションありがとうございます🤗💙❤BESTY

Hardcore Atiny here and ready to add Be:First to my list. Need the bts on this STAT bc I’m gob-smacked to the point of calling it the best collab of 2024. IMHO.

Awesome sauce!

hush-hushリアクションありがとうございます。去年、BE:FIRST所属のBMSG主催のD.U.N.K. FESでATEEZと共演してから仲良くなりました。こんなに早くコラボレーション見られると思ってなかったのでとても嬉しい驚きです！15人もともと同じグループにいるかのような統一感にとても感動しました♪ BE:FIRSTに興味持っていただきありがとうございます。ご存じの通り彼らは7人が高音も低音も歌唱しますしラップスキルが高いです。彼らの歌声を楽しむならTHE FIRST TAKEのBye-good-bye , Smile Again , 公式ライブ映像のSalvia お勧めです。7人のラップスキルを楽しみならMilli-Billiお勧めです。どのMV映像も楽しいですし、ライブ映像は圧巻です。どちらも公式で見られますのでリアクションお願いします♪

リアクションありがとうございます❤

reaction(⁠≧⁠▽⁠≦⁠)ありがとうございます❤️Thank you so much🎶🕺✨BE:FERST×ATEEZコラボ最高⤴⤴🎉Sky-Hi💕BMSG✨

Thank you for giving info about Be:first. I must check more of their song a collab should be so seamless, it sounds like they are one team instead of 2 ❤❤

あなた方の誠実でリスペクトすら感じられるリアクションに感謝しています！ BE:FIRSTの存在意義を認めてくれた愛のある言葉にも感謝します！

Yo Guys, ATINY was Waiting for This. Please then React to Dear Name form Jongho and San. You Will enjoy that

Hii!! Great reaction! If you liked this, please check out more BE:FIRST! Song recommendations: Gifted (the orchestra version is my roman empire and you can hear their improvement so much), Boom Boom Back, Mainstream, Masterplan, Smile Again (The live performance from DUNK is sooo good), Salvia (Live), Bye-Good-Bye, and Milli-Billi! The members ages range from ‘98 to ‘06 (The youngest is 17 until November, but he’s the only minor and only teenager). They’ve been active since 2021 and were formed through BMSG’s “The First”! Please, please, please check them out!! They are so talented and deserve so much more recognition! :D

BESTYです! リアクションありがとうございます!

Oh my God i said the same thing that someone in BE: FRIST sounds like jongho

リアクションありがとうございました！BE:FIRSTやSKY-HIのオーディションの紹介等ありがとうございました！ 私はBE:FIRSTのファンですが、ATEEZもカッコよく、このコラボは夢のようで毎日興奮し続けています！！

動画のはじめから編集が楽しくて、最後までみたいと思いました。 おふたりが声を上げる箇所が自分とは違ったので、その反応も楽しかったし、とても細かく感想がきけて嬉しかったです！

I definitely agree that or leans NCT. Something about it reminds me of 127s Gimme Gimme.

リアクションありがとうございます BE:FIRSTに注目してくれて嬉しいです

Thank you so much your reaction! Amazing!!

🫶

This collaboration is so well done. The way they paired voices and made sure all the members of both groups had lines. It wasn’t a group with another group featured for two lines, it was a true collaboration

Please reaction Gifted.-orchestra- and Milli-Billi live ver and Boom Boom Back live ver🔥
