Isn’t it obvious why he did it? He did it to convince joonhyuk he was on his side to manipulate him. So he could betray him in the present.
He and the MC aren’t in any kind of relationship so it’s not cheating. Also there will be more manipulation by Kang Moo with using other people in the story so get used to it
Why did kang moo finger joonhyuk?? Like what was the point of him doing that even though he said he was uninterested?
