Weird of me to say this but she's now giving him one sided pleasure like a BJ instead of just sex, plus she says she can't sleep so she did that? That's some "interesting" way to show gratitude.
Looks like things are wrapping up and Kanoko got her confidence back. Wonder if she got that "acting chairman" to ally with her or something. I doubt if she's smart enough to successfully negotiate that way to someone who's all business but maybe there's a blackmail or two.
