Kouhei decided to go ahead with the quest to seduce the nun.
He didn't want the whole thing to come across as overly stalker-like, even though he had to admit that he was technically following her at the moment. There was a rather uncomfortable difference between secretly observing someone because of a quest and openly walking after them like some suspicious guy who had apparently forgotten how normal human interaction worked.
Because of that, Kouhei was making sure that he didn't get too caught up in what he was doing. If he became careless, he might end up eating more than he had bargained for, and he wasn't particularly interested in finding out what kind of trouble that phrase could actually lead to.
Kouhei thought the woman was rather strange from his perspective.
