I actually liked the chapter. I still don't know if the boss is more manipulative bitch or simply too naive and stupid, and I agree that long term she's probably not be good girlfriend material, but I totally understand Yoshida giving her another chance. After all, he liked her for years, he still hasn't truly moved on and he's suddenly given a new hope. In these kind of situation, it's hard to be 100% rational and not simply follow your feelings. At least he called her for her behaviour and he put on her the burden of confessing if she really is serious about him.
