They could claim BYG has a throat condition so he can't perform live while he recovers, so sad, and turn up the backing track for his parts! (I suppose BYG could handle Himchan's handful or lines per song....) I'd be more worried about what Himchan would do to/for BYG's image during interviews/radio shows... although if he's not supposed to rap for health-related reasons, then I suppose he's not supposed to talk, either, so maybe that would be alright. Himchan might come off as unusually subdued during these hard times. Perhaps shippers would decide it's because he's depressed over BYG's poor health and misfortunes and take it as evidence of their forever love!!!!
