    Jaejun was the first idol close to my age when he debuted with C-Clown back in 2012. I remember being so excited LOL. I’M SO HAPPY TO SEE HIM ACTIVE AGAIN. <3 I can't wait for Trei to officially debut!

  • S.


  • suga.topia

    I do believe so. Every website I’ve looked at said they debuted in March.

  • S.

    Oh! That’s strange. 😮 I know they released some tracks but I never thought it was official! I don’t think they promoted either…?

  • suga.topia

    All depends in if they have money to promote their songs.

  • SAAY


    Jaejun – Leader, Lead Vocal, Visual, Main Dancer
    Juntae – Main Vocal
    Changhyun – Rapper

  • Mrs. Choi

    a new article was released from Korean news and retweeted by TREI’s official accounts- it says they their official/formal debut will be in early 2019. so their debut hasn’t been official until now (personally i think they’re just regrouping and calling this one their official one since they didn’t take off immediately but banana culture says the 2019 date will be their formal debut)


  • Mrs. Choi

    new article shared by banana culture says they will debut early 2019. it was just released

  • KProfiles

  • Markiemin
  • Tierney Wheeler

    Is Changkyun foreign or at least half? He just doesn’t look…. Korean?

  • Minhyuk-Sunbaenim 🌹

    shouldn’t changhyun’s position be MAIN rapper since he’s the only one…

  • Christian Gee Alarba

  • Nathan James

    Jaejun my hunny bunch luvvy bunch <3

  • YoongisGummySmile

    They have chosen the group name TREI because of the Romanian word ‘trei’ which means three. They chose it because the group if formed of three members 💖 I am Romanian 💖😊

  • OkxyAmi

    Oml I was so glad when I heard that their name is from romanian :)))))) . First bts mentioning Romania, now trei choosing their group name as a Romania word. I am also romanian :)))) 💜

  • ImanKook

    Hurts when these beautiful boys weigh much less than you and you are half their height !!

  • jiminwifeu

    gravity is really good song! juntae is already become my bias because of his beautiful voice^^)i hope this group can get more attention ^^)

  • 송수연

    Astin also made their debut this year and their first album is on a crowdfunding project on Makestar. Please make this happen!!!

  • SammyBaby

    I wouldn’t worry about it too much because kpop companies are known to lie about their idols weight and take off a few kg and their height and add a few cm, plus kpop idols are always exercising and have extremely strict/unhealthy diets hence why a lot happen to collapse on stage for example SISTAR Soyo once only drank water and ate cucumber for a month, not very healthy

  • Ameylei

    Changhyun was born on the same day as me 😆

  • cierra

    Changhyun doesn’t like horror movies

  • Maru 💕😍
