Takasu Ryuuji has learned the hard way that appearances can be deceiving. Despite his inwardly sweet personality, his unintentionally sharp gaze and aggressive features give him the air of a delinquent thug, putting his chances at making friends, let alone a girlfriend, next to zero.

It's Ryuuji's first day in junior high school and it seems as if things are looking up. He gets to sit in between his only friend, Yusaku, and, more importantly, the girl he's secretly crushing on, Minori Kushieda. But just when he thinks the stars are aligned in his favor, he unwittingly crosses the most feared girl in school, Taiga Aisaku, making her onto his arch enemy. To top it off, Taiga has moved in right next door to Ryuuji and happens to be Minori's best friend! Can this school year possibly get any worse?!
