Three geniuses, one apartment, and zero survival skills."

Mikoto Asada was once a rising star on the tennis court, a prodigy with a racket—until the pressure and an abusive past shattered him. Now a twenty-year-old college freshman, Mikoto just wants a quiet place to sleep and a way to avoid the panic attacks that strike whenever he hears the squeak of a sneaker on a court.

But the campus dorms are full, and his only hope is a live-in "Caregiver" position for the university’s most elite trio: The Kodakawa Triplets.

To the world, they are the "Princes of the Campus":

Marin: The rising starlet with a killer smile.

Karen: The ace athlete who dominates the court.

Shino: The future doctor with a genius-level IQ.

But behind closed doors? They are a nightmare. Their apartment is a disaster zone, they can’t cook a piece of toast without a fire extinguisher, and their "perfect" lives are held together by Scotch tape and secrets.

Mikoto’s job is simple: Clean the mess, keep them fed, and stay out of the spotlight. But when Karen forces him into a match that triggers his darkest memories, the masks begin to slip. Can a broken athlete heal three "perfect" girls who are falling apart—or will their shared chaos be the one thing he can’t manage?
