I really do not like these kinds of stories. Everyone seems to fault the tsundere girl for not being okay with the move. She's essentially getting abandoned by the person that she's in love with and has no recourse for it. Why are people just supposed to accept that it's alright for the other girl to fly off with little warning and expect the other party to not get hurt over it? The MC is a countryside girl. That's her home. And she's still in school. It's not like she can just run off to the city because she wants to. The girl leaving comes off as very selfish and self centered. If a person wants to enough, dreams and goals can be accomplished without leaving behind the people you love.

Damn it. I want to see their relationship take a more physical turn. We've had enough drama, time for some sexy time!

Yandere tag?

My best guess about the vase was; since she was under the assumption that she was being stalked, she was speaking about the practice of putting a vase on the student's desk to indicate they have died. Perhaps indicating that she would be killed by her stalker at some point?

I just created an account to say one thing:
Fuck you Mew's "dad".
I had a serious rage moment there and I'm not even gay. Anyone in real life who could walk away from a talk like that and stay even semi-composed would make me incredibly impressed. I'm about to go punch a kitten just to let off some steam.
Mew's dad, seriously, go die in a fire. Seriously.
