Dame Inu Kanojo

Sakurako Kuramochi has totally remade herself into a more popular girl since her debut in high school.

However, deep down inside, she still bears the scars of being dumped by a girl she used to like.

One day after school, while walking downtown, Sakurako bumps into another girl, who turns out to be that girl who rejected her in the past!

For some reason, she proclaims that she's fallen in love with Sakurako at first sight, and asks if they can meet again.

Sakurako gets angry at the girl for not recognizing her, and comes up with a plan to get revenge...?
