She's really unlikable. Poor dude should just find someone else.
She's not that bad really. She's cute, she clearly likes him and her tsun moments aren't all that violent compared to a
TSUNdere like Louise from

horny moments when sitting on top of him, those probably make up for a lot of the abuse.
