Before yesterday I knew nothing about Be First. Today I did some research. Ateez debuted in 2018 and Be First debuted in 2021 only 3 yrs later. Ateez members are all relatively close in age 24 and 25. Be First is on average a few years younger. If you read about each group’s members, you find they very closely parallel each other in personality. Both groups have similar vocals, rapping and dance skills and crazy popular in their respective countries. I’ve been an Ateez fan for about a year now but I think Be First could grow on me. Don’t worry Seonghwa, you’ll always be #1 for this grandma who wishes she was 40 years younger. 😉 Almost forgot-Fun Fact: Sota was a background dancer for Ateez at KCON-Japan in 2019.

Thanks for the reaction. ATEEZ is a K-pop group though, BE:FIRST is a Japanese boy band! This song is available on BE:FIRST's official channel. Please check out our other songs!

This is atiny. Of course the song is great, but MV is Surreall! ! There are so many people, and yet each one with their talents, in fact, the charm of each person is exploding, optimal voices of the Be: First! In addition, those who called the two groups to this MV deserves a triple increase, is as if they had left a fashion show! Many thanks to be: first and sky-hi for this wonderful collaboration. I have always been sure that dance and music can easily cross borders. Ateez, literally broke the glass barrier to join Be: First. My God, what an amazing video, what a sick bit, and that wonderful voices meet next to Ateez. I'm Atony, and now Bestiny. So proud of all of you, I'm reaching and now better. Thanks for this collab, iconos. ATEEZ/BE: First. Thank you for your great reaction.⏳🔥❤👏👏👏

Thanks so much for reacting to this collab!! International BESTY (BE:FIRST fan) here BE:FRIST has a fantastic discography, and it would be fun to see you react to other releases too! Their latest single Masterplan is great and the MV is crazy. And I would also recommend Scream or Boom Boom Back. And if any questions come up about them, I am happy to answer 🙌✨

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♪ Amazon primeに入会していると去年日本国内の映画館で上映されたBE:FIRST ドキュメンタリー映画と今年3月2日 3日、東京ドーム公演のライブ映像が見られます 字幕もありますのでぜひチェックしてください！ そして！そして！2024 ATEEZ WORLD TOUR [TOWARDS THE LIGHT : WILL TO POWER]IN LOS ANGELES 2024.07.20&21 Los Angeles "BMO Stadium" BE:FIRST スペシャルゲスト出演決定しました！彼ら15人がライブで観客を魅了します！

Thank you for your reaction💕 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 :D.U.N.K.Showcase, and it was so cool. I also participated in the BEAT AX Vol.4 event at Makuhari Messe in Japan on June 28. ATEEZ appeared for the last time. I was overwhelmed by them. Their performance was wonderful. 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. From Besty❤️🇯🇵

Thank you for the best reaction❤️‍🔥🎶

Thanks for reacting. Please more react to ateez

Thanks for the response ♡. Both are very nice! Keep an eye out for BE:FIRST! And listen to the other songs ♡. I guarantee you will enjoy them!😊😊

First time seeing this! Besides the Kingdom Legendary Wars, I haven’t seen whole groups collab! This is cool to see.

My favorite part is Hongjoong kicking the window in, both the visuals and just the general sound of the song around it as they are dancing on the trains.

楽しいリアクションありがとうございます！！思わず私も笑顔になりました！😆

ありがとうございます🤗💙

Ateez has no chill

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

Atiny here! Loved the reaction!! The second guy with the vocals that you liked? His name is Wooyoung. And the last guy in that vocal line who hit the really high note is Jongho, the youngest of the group (maknae) ☺

5:25 I think they're saying hush hush probably, just softly.😂 It's catchy though.
