Taekwoon cried a lot when hakyeon found out about his ability,probably scared that hakyeon would be freaked out and leave him.But hakyeon didn't.Nor did the others.
Jungkook didn't know when it happened. There wasn't a single definitive moment that made him realize that he wanted more. He just knew that he did. He wanted Jimin in a way that he shouldn't want him. A way that a dongsaeng shouldn't want his hyung.
