I'm totally behind the idea that she just doesn't think she's worthy, but her behavior isn't unlike a clingy mom either.
Deducing everything about the potential girlfriend and worrisomely wanting to check her out further...ayup.
Well, I don't think Minoru has anything to worry about. He'll know the girl is a keeper if he lets her know about his living situation and she decides to stay. Assuming this isn't some mean prank altogether.
As a side, can I say that I appreciate the continuity this story has? Every chapter seems episodic, but the thought process always connect the end of the previous chapter to the start of the new one.
