Will the MC ever grow any balls? He's basically spitting on his grandmother's face by behaving like this. He had a week to get prepared for this meeting, but anyone can see he did absolutely nothing. The catering was also probably handled by Chikage. I bet the dull MC did nothing but sit in self-pity for the whole week. Or perhaps he at least took a broom and cleaned the courtyard. He's so bloody annoying. I can't imagine the mangaka would think readers would actually like him, huh? Surely not?
Isn't the teacher bothered at all by his partner trying to hit on women left and right? I assume the teacher himself is pure homosexual, but the quarter vampire is clearly bi since he does show interest in women as much as in the teacher.
