Mostly about the guys reasons, like ok he is going to create a scandal to piss his dad off, I get that. Not sure why he just got it on with the other guy who said he was his best friend. He actually seemed not to like him or at least didn't want to kiss him. So I just didn't get it. I'm sure or at least hopeful it will get explained more later.
he dose wan't to take revenge on his father but all his being there in fighting club or whatever that place was is a coincidence & he said he fell in love from 1st sight & decided to use him but in the same time his obsession is growing & want to know his past. for the other guy was interested in him & knowing that he already had sex with a man he asked for sex as price for the information about the past so he agreed & made it clear that it was only physical & no kisses or any other emotions in there. about the past .. the guy was the right hand of yakuza leader that had been killed & the group disbanded & he was kind of sold to that fighting club .. now he is looking for the left hand guy cause he was the one who betrayed the boss & caused his death. i hope that makes things more clear
Oohhhh ok so he didn't want to kiss his best friend becuz he doesn't like him of course. The only reason he let Choi kiss him because he actually likes Choi. And he's only letting his best friend f*ck him becuz he made a deal if he let's him f*ck him then he gets information about chois last owner. If that makes sense
So far this story is confusing.
