His childhood friend Takanishi Aisa is a popular beautiful girl even when the two were in school. It’s not a surprise that they now are estranged. But, Aisa have only had eyes for Kouki…? As Aisa’s younger sister Minami’s home tutor, the two once again come into contact. It’s a romantic comedy about the unfriendly class idol Aisa and Kouki who is afraid of that cold attitude.

The protagonist begins to get involved with the most beautiful girl in school, who is famous for her cold attitude, and slowly becomes attracted to her. That protagonist finds himself in a consulting relationship with a plain girl in glasses at his part-time job. He doesn't realize that the girl he is consulting is the same girl he is in love with, and just keeps telling her about his growing feelings while continuing to fall in love with her. The heroine realizes that the person he is in love with is herself, and although she is embarrassed by the protagonist's feelings, she gradually becomes attracted to him.

Hina Airi, a senior one year above me, is renowned as the most beautiful girl in school. To me, Masahi Shuuma, she’s just my sister’s friend—someone I barely know beyond a polite nod… or at least, that’s how it was supposed to be. "Looks like I enjoy spoiling you, Shuu-kun." It all started when I visited her house to check on her while she was sick. Since then, Hina-senpai has been closing the distance fast—homemade meals, dates, lap pillows… "Hey, I want you to teach me more. Why does my body ache for you—?" She shows me a side of herself no one else gets to see. Before I know it, we’re in a temporary relationship!? "I’ll make sure you can’t live without me, so you’d better brace yourself." A romcom where my senpai pampers me into blissful ruin! (Source: Kadokawa, translated)
