I think he's completely aware of that tho
He's still an idiot for thinking this is gonna make her take him as a partner like no man, she isn't gonna date you bc u kidnapped her LITTLE BROTHER and treated him like a guinea pig
Don't forget that he already sold out her info that she had that doctor/scientist in her custody too.
SORRY MEANT TO UPVOTE!!
Bro I don't get why he's not just helping jiyoung out and trying to get closer to her like were you planning on pretending to save his brother??? But then why are you actually doing experiments on him
the kid you kidnapped is literally THE YOUNGER SIBLING OF THE GIRL YOU WANT TO MARRY WTAF ヽ(`Д´)ﾉ
