Is this manga supposed to be a subversion of romance manga that shows somebody bent on romance instead just finding a friend?
It sounds nice, but I wanna see them together!
I think the reflection is her true form? Art collector lady is probably some kind of demon trying to use the power of the creepy cats to achieve new heights of power or regain her true form or something.
Everybody's talking about how returning the book doesn't make him a better person but like, he's a dumb kid? We were all irresponsible in high school and could be insensitive at times. I guarantee that anybody who had friends in high school can look back and imagine plenty of circumstances...
