There are three simple essentials in life: a handsome face, a healthy body, and an exceptional mind. Kirishima Toru happens to have all three. Reborn for over a decade, he thought he could become a heartthrob in Tokyo, graduate from the University of Tokyo, and land a civil service job. But then national idol Minamoto Aine discovered his secret side gig as a rental boyfriend and blackmailed him into becoming her tool for enjoying the thrill of an affair.
That alone would have been bad enough, but what drove him to despair was that Aine's partner, Saionji Chiba, found out he'd been cheating with her!
Just as Kirishima Toru thought he was done for, the perfect, proud, aloof young lady of the Saionji family, doted on by everyone, blushed and trembled as she asked, "Can I join in...?"
"Huh?"
A certain landlady: "Lately, Toru's room has turned into a full-on O room."
