This is actually really sweet. He knows her well enough that he observed she was nervous pretty quickly. She's not thinking less of him because of his room; she has a super-uptight upbringing (hinted in previous chapters) and is extremely nervous being in his room.

Pretty dang wild how such a simple webcomic can be such a strong performer. The premise is intriguing while also having some warm fluff content too. I'm curious where this goes and want more story.
There is no tsundere or yandere though. She's stern and stoic, but is still involved in the relationship. She doesn't admonish him; the only times she had objections to something she quickly made an alternate suggestion.
