they fr did so good on blending the 2 groups together , im obsessed

Yes, Be:First is a Japanese group, I love how seamlessly they blended three languages together. Also one of the members of Be:First, Sota, was a dancer for Ateez in 2019 at Kcon, so they've known each other a long time!

Both groups just announced today that Be:First will be the special guest at the LA shows. I wish they'd go to all stops. I want to see this live.

Thank you for the reaction! Happy ✨ BEFIRST & ATEEZ is the best! BEFIRST is Japanese Dance & Vocal Group! masterplan ＆ MainStream Please take action ☺️🎶

Please check out more of Be First!!! They are amazing. Yes from Japan. Master Plan and Mainstream are a few great M/Vs to include!!

OMG! That chorus is really addictive!! Hush Hush!! Thanks for reacting to this collab! ❤ I love that YOU love ATEEZ so much!! And yes, I think you should check BE: FIRST, too...I've heard their song "Mainstream" is pretty good...

Congrats on getting sponsors guys! Also, you need to react to BE:FIRST. I didn't know who they were but after Hush-Hush, I checked out their songs and yup... they got me. Mainstream and Masterplan are the 2 songs recommended the most, but they have a lot of good stuff.

thank you🇯🇵

Honestly this is the most cohesive, well blended collaboration I’ve ever seen. Most times a collaboration is so unbalanced and just like someone thrown in for a bit to be able to call it a collab. This was so well balanced it was as though they were one group not two. ❤🔥

Be first -mainstream 100%%%%

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 the reaction😊🇯🇵

Nobody can break their back reacting to things as good as Caitlyn does. You guys would have a fire collab with her

Loving the new Work intro music 😊 BTW they just announced that Be: First will be appearing with Ateez at their LA shows. So Hush Hush live version soon!

ありがとうございます🤗💙❤

リアクションありがとう🤚 ATTEZとコラボしているのは日本のボーイズバンドBe:firsです。色々なジャンルの曲を持っていますが MasterplanとMainstreanがおすすめです。 あなた達を待っています🫶🇯🇵

リアクションありがとう🙌😁🎶 It's a real science-reaction collaboration song 😱❤️‍🔥

Thank you for your reaction💕You guys‘ reactions were a lot of fun. Yes,BE: FIRST is Japanese boy band. 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 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."You guys are at the core. 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. From Japan ❤️🇯🇵

リアクションありがとうございます😊 BE:FIRSTのライブはPrime Videoにて 『BE:FIRST LIVE in DOME2024“Mainstream―Masterplan”』 の世界配信が開始されました😊 ジャンルレスで、ライブが魅力的なグループです✨ 2.5時間位あるのですが、LIVE中に歌っているイギリスのジョナス・ブルーさんとのコラボ曲、 「Don't Wake Me Up feat. BE:FIRST」も個人的に好きです。

Collab of the year!

this collaboration was fire. also, I love Freddy's faces every time JongHo hits a note🤣

Thanks for the reaction! I was excited to see you reacting to Hush Hush! This collaboration was awesome, it was a true 50/50 between the groups 😊

BE:First is going to be special guest at the LA show! I am so excited to see them. That is legit crazy because Japan is hella stingy with her groups! The only group I know outside of &Team is INI and only because they come to KCON LA. It's rare that they tour or come out in any festivals. And yes that is me. I am deep in this reactor ish because I know exactly who you meant when you say "Ayo!" Lol!

Ayo bubbles!!! lol I love her reactions as well ❤❤❤ Another great reaction guys! I hope you check out be:first at some point. They are phenomenal dancers, singers and rappers. I’m so happy Sky-hi asked Ateez to do this collab after their invite to the D.U.N.K. Showcase, because frankly it’s probably one of the better (if not best) collabs I’ve heard this year.

I got a great news . “2024 ATEEZ WORLD TOUR [TOWARDS THE LIGHT : WILL TO POWER] IN LOS ANGELES 2024.07.20&21 Los Angeles "BMO Stadium" BE:FIRST special guest appearance decision” Then,finally, the BE:FIRST's live video of Mainstream at Tokyo Dome performance has been released ! Please react it. Their live performances are amazing ✨↓ “BE:FIRST/ Mainstream -from BE:FIRST LIVE in DOME 2024 “Mainstream - Masterplan”-【Prime Video 配信中】”

Choreographer is RIEHATA! She choreographed Ateez on Pirate King and appeared on their predebut video! She's amazing.

有り難う👍🎌😘
