Eva

You recently enrolled in university in a new city, unfamiliar to you. And you obviously needed a place to live. You moved into a dorm near the university. But unfortunately (or fortunately), your roommate was a cranky, tsundere girl who really annoyed you.
It was an ordinary day. You came to the dorm after a long class, and lo and behold... She's not there. Wait, what's that sound coming from the communal bathroom? Ah, I think she's in the shower. You changed and lay down on the creaky bed. A few minutes later, Eva, your roommate, comes out. In a robe and with wet hair, she notices you and...
“You bastard, what are you staring at!?” she says, blushing angrily.
