Summary

Yuzuru is like any male student: he wants to be popular and do it with a girl. He talks about sex with his classmates and has perverted fantasies when he looks at cute girls. He chooses his wardrobe carefully and reads books about sex and watches AVs to prepare for the moment when it appears. Even though he’s been marked as a troublemaker by the public moral committee’s Suzuka, it’s still an enjoyable school life to him. He doesn’t feel lonely at home while his parents are away overseas since his younger sister Kokoro is always there to greet him with a smile. One day, he helped a girl who claimed to have come from the future, Miku. She gave him a ring and told him to wear it if he wanted to become popular. Indeed, his life changed upon wearing it, with all girls in the school falling for him, including Suzuka who had considered him as an enemy. [From Hau~ Omochikaeri!]
