Nah, he's still a dick. I'm sorry, but he kinda deserves this hate. He's clearly using DG for his body, not necessarily caring about his feelings. DG is clearly naive (sort of innocent as well like most virgins). Jiwon (Alex) propositioned him for sex, at least make sure DG's first sex is gentle and memorable. Even though DG agreed to it, he's still using him for sexual gratification so he can make money during his show. Even after taking his virginity, he didn't make sure he was okay the next day (as much as I enjoy yaoi, anal sex hurts especially the next day, I read the raws, he doesn't check on him) I like Jiwon (Alex) but face it, he's a douche.
Give Alex a break lol I really think Alex likes him
