Atsuhiro "Akkun" Kagari is crazily in love with his girlfriend Non "Nontan" Katagiri. However, instead of showing his feelings, he hides them under a tsundere mask and prefers to store her photos and voice in his phone.
Atsuhiro et Non sortent ensemble, mais leur relation a l'air un peu particulière.
男子高校生の荘敦大（あっくん）と女子高生の片桐のん（のんたん）は恋人同士。しかしあっくんはのんたんに対して、いつも罵詈雑言を浴びせ、“ツンツン”な態度……。今日ものんたんが「一緒に帰ろう」と誘ってくれるのに、あっくんは「話しかけんな」と追い払ってしまう。だがのんたんが教室を出るとあっくんは無言でカノジョのあとを追い始めて……。
Akkun não é um namorado como qualquer outro, mas Nontan o ama mesmo assim.
