Usotsuki Ambivalence

Amamiya Ichika, a girl with excellent grades, has a rival she detests: the top-scorer and cold-hearted student council's vice-president, Kizaki Tsukasa. While Ichika, in a flashy disguise, is working hard at her part-time job which is against school rules, Kizaki appears! Ichika introduced herself as Futaba to deceive Kizaki, but to think Kizaki fell in love with Futaba at first sight ★

Is this the start of a double life that can't be exposed...?! The curtain is raised on this misunderstanding-filled school romance!
