I'm enjoying what the new teacher brings to the table far more than I had expected when she was initially introduced. I dreaded the fact that she might be another rival, but she is a hell of a wing-woman; far more than the sporty girl who's obsessed with our dear CEO/Fashion Icon/IT-Girl.
This was a real cute chapter, to boot. Her blush and happiness when she realizes he's been paying so much attention to the day she dresses was very, very sweet; and not over-done like so many mangas would have done it.
