Ha ha. I already like tsundere's (unless they're in harems, then that's usually the only personality trait they have), but this girl is on another level. She's fricking accidentally grouping herself than banging her head against a wall and screaming baka. It's like when the tsundere finally falls for the protagonist after season 6969 and it starts showing her inner monologue. Except it's the first chapter and the main character has done nothing to make her like him. I like this.
