Hahaha! These last two chapters are proof of Hata-sensei's marriage. It is amazing how you can say something innocuous that will piss your woman off, and how you can say something complimentary of her, and she'll act like what you said was nothing special, even though she loved it. Of course in the latter, she might show her appreciation that night in unexpected ways. And in the case of the former, she might use that against you in a disagreement about something.
Nasa has the right idea. If something you need to do is hard, you don't give up. He accepts that this is something he needs to practice at and commits himself to it.
