Minori, didn't you hit Tarou a few chapters back? Where is your violence now, you could have easily slapped that crazy stalker to stop her in the middle of her dumb "I know you" speech.
Fuck, it makes me angry. The whole victim blaming she does, her insulting Umi for being a decent human being who wanted to give her a second chance, talking as if she knows who Umi is deep down when she met her twice and doesn't know shit...
Just report her, so her ass can face some consequences and she can get her shit together.
