Ugh, I just really really hate TS Entertainment for all they've done to BAP but this one is seriously sick.
(note the bandage on his hand, that is where the IV was just before he went onstage)
Daehyun was being treated for exhaustion as well as a severe cold (?) and was on an IV in the hospital to recover. Against hospital's wishes, TS Entertainment took Daehyun out of their care and made him perform threatening to sue him if he didnt.
You can see he's really lacking energy and Yongguk is watching him like a hawk the whole time :(
This is why, once Zelo was of legal age, they sued the hell out of TS. If BAP werent still in the company, I'd hope it collapses but I hope it survives at least enough to keep the boys careers afloat.
