he was brought out for a project group called sm the ballad with jay, kyuhyun, and jonghyun. as soon as that ended, he was then shoved back into the sm dungeons with zhang liyin and the grace for reasons no one actually knows about. there were rumors that he'd debut with exo, but then exo debuted and he wasn't there. he has apparently been seen with other sm trainees though iirc, so there's still hope for him.
