Tadanori Date

Kisaragi Amatsuyu is invited out alone by the cool beauty upperclassman Cosmos and his childhood friend Himawari. Expecting to hear their confessions, he triumphantly goes to meet each of them in turn. But Cosmos and Himawari both instead confess to Amatsuyu that they like his friend. Amatsuyu fights this lonely battle, but there is another girl who is looking at him. She is a gloomy girl with glasses and braids. Amatsuyu finds that he hates her, because she's always turning her sharp tongue only on him and finding enjoyment in his troubles. But it turns out that she's the only one who actually does like him.

As a child, Masamune Makabe once suffered greatly at the hands of a wealthy and beautiful girl named Aki Adagaki, who nicknamed him "Piggy" due to his chubby appearance.

When he encounters Aki once again, he is prepared to exact vengeance. With the aid of the rich girl's maid, Yoshino Koiwai, Masamune slowly begins to build his relationship with Aki, intending to break her heart when the time is right. However, as his friendship with Aki begins to grow, Masamune starts to question the objectives of his devious plans, and if bringing them to fruition is what his heart truly desires.
