Yoo-jun definitely. He was clearly messed up in the past due to his ambiguous entaglement with Eunsong and I believe his destructive behaviour were mostly because of the confusion. Anyway, now the cursed bond is broken, his head will be clear enough for him to start making sound decisions. So, yeah, he is the worthy end game not that crook Eunsong.
So, a million dollar question, team Eunsong or team Yoo-jun?
