In the eyes of those fan girls, the tensai Oshitari Yuushi was not only famous for his tennis skill, but also for his charming smirk. That smirk of his had captured (almost) all girls' heart, including those that already had a boyfriend. And Oshitari was very proud of it.
Until one day, he met Tachibana Ann, the only girl who wasn't charmed by his smirk. Since that day onwards, Oshitari decided that he would chase her, since she was an interesting character.
Yet, no matter how he'd tried, Ann still doesn't seem to fall for him. Instead, he'd realized that; the more time he spends with her, all the more he found himself falling for her.
'Maa… one day you're be mine, Ann-chan.'
