The new semester has begun. The boy Takasu Ryuji (voiced by Junji Majima), who looks fierce but has a pure heart, is determined to use the opportunity of reclassification to sweep away the misunderstandings of his former classmates. What makes him even happier is that he is about to become a classmate with Kushieda Minori (voiced by Horie Yui), who has been secretly in love with him for more than a year. In addition, he is accompanied by his long-time friend Kitamura Yusaku (voiced by Nojima Hiroshi), and a new high school life is unfolding in front of Ryuji. The appearance of the girl Osaka Taiga (voiced by Rie Kugimiya) attracted Ryuji's attention, not because of her arrogant and black-bellied awkward personality, but because by chance, Ryuji discovered that Taiga was secretly in love with his friend Yusaku. After confessing their secret crushes to each other, Ryuji and Taiga decided to form a unified love front and use each other's help to complete their respective love blueprints. But the reality is not as simple as imagined. Amidst the heavy misunderstandings and twists and turns, the two seem to have developed feelings beyond friendship for each other.
