Yoshimatsu Hotaka is the president of the manga club and is always diligent with his school life and club activities, but even though he looks like a regular honor student in reality we have that there is something really odd with him; he has this bitter ~ heavy ~ melancholic look and is almost always looking at Awaya Niki, the beautiful, bright, radiant, super cheerful swimming club's female ace. Why does Hotaka act all bitter like that? And what will become of him as the sports teacher orders him to have at least 'one secret swimming class lesson' where no one is supposed to be looking, whereas he normally skips class activities due to personal matters?

Takasu Ryuuji has learned the hard way that appearances can be deceiving. For 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 new friends, let alone a girlfriend, next to zero. It's Ryuuji's first day of his second year of high school and it seems as if things are looking up. He gets to sit in between his only friend, Yuusaku, and more importantly, the girl he's secretly crushing on, Kushieda Minori. But just when he thinks the stars are aligned in his favor, he unwittingly crosses the most feared girl in school, Aisaka Taiga, making her into 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?!
