This is written as if you just were signed to a company and just started training (so like pre-debut)

Seokjin
Jin would be so proud of you! He would be by your side throughout the whole process of training and debuting. He knows how tough it can be and wants you to know that someone is in your corner, rooting for you all the way.
Yoongi
After you told Yoongi you were becoming an idol, he would immediately go into logistics. Similar to Hoseok, he’d want to know everything about your group. He’d really want to know who was in the group and your position. After explaining you didn’t know any of that yet, he’d just tell you how proud he was.
Namjoon
He would be proud but a bit wary. He’s glad that you took charge of your life and decided to something you enjoyed, but he knows how harsh the idol life is. Besides how worried he is, he’s 100% for it and willing to help you as much as he can.
Hoseok
This boy would be even more excited than you! He’d be off the walls excited. He’d want to know when you’re debuting and with who and what your group is called. You’d need to remind him that you were just signed and you didn’t know yet. He’d be your biggest fan.
Jimin
Jimin would be happy and would offer to help you out. You need help learning a dance? He’ll help you. Need help with singing? He’s there in no time flat. This boy just wants you to be successful and he’s willing to do anything (within his abilities) to help you achieve that.
Taehyung
He’d be excited because having you be an idol too means you guys can spend more time together. Yes, he does know that both of you will tour and be away for long periods of time, but also you guys can go to award shows together and do stages together.
Jungkook
While being extremely proud of you, Jungkook would be kind of sad. He knows that you would be busy all the time with training now and even after your debut, you’d be busy with practice and performances, like how he is now. Despite this, he’d be happy you’re doing something you love.
