Kurumi Yoshizawa, the student council president, has excellent grades and an inviting, friendly personality... on the surface at least. In reality, her days are spent struggling against her domineering mother and agonizing over her teachers' expectations. One day, Kurumi reluctantly goes to meet Naoi, her truant classmate, at her homeroom teacher's request to look after her.

Average company worker Shimono spends his days constantly being helped and scolded by his superior and section chief Kamijou Touka. One day, he finds himself having traveled back in time to his high school years. He sees this as a chance to aggressively approach the section chief a second time around, only to find out that very woman had turned into a girl constantly acting lovey-dovey towards him!

This school is full of relationships, with students and teachers each with their own secrets. (Source: U-NEXT, translated)
