Did na seungwoon imply that he's done *things* with secretary Kim? I'm just checking to make sure I read that correctly

^^ I don’t think he meant it literally that they ever did anything. I believe he meant it in a way that he has to go on all these dates with higher class woman, according to his mother’s wishes. And so the secretary wants what his mother wishes for, so I assume she’ll do anything, that includes making giving him a deal to investigate his rival in exchange for doing as his mom wants

What happened to honjou trying to get even with her sister?
And it's sad he hasn't had any other "experience" that he can draw fantasies from aside from that nasty teacher. I mean, a resourceful boy would substitute a different person in the same situation... But it seems he preferred the reality over a fantasy. He needs to get (consensually) laid.
That letter is NOBODY'S business...
