Aoi Nishimori is a high school girl who lives alone in her own apartment, but to her surprise, she discovers that the prince of her school, Shusei Kugayama, has moved in next door! To add to this, a series of crazy happenings result in the two living together under a single roof! Shusei is known to be a heartless guy and Aoi particularly hates him after he coldly rejected her best friend, so a life of cohabitation seems like a recipe for disaster. And yet, Aoi somehow can’t stop her heart from pounding when she’s with Shusei…
It’s back to school after a summer full of love for Aoi and Shusei! While they keep up the charade of hiding their relationship and living arrangement, an unexpected player joins in on the game. Shusei’s cousin, Leon, from America surprises them—and it’s to the delight of all the girls at school, too! The boys have a score to settle and the stakes are high for Aoi. Will Shusei up his game to prove his love for Aoi—and can she meet Leon’s high standards for acceptance?
