Kurono Teppei

He did not even attend school because his parents were posted abroad and were not at home. He is an ordinary boy living a NEET life.

He likes Yurika, a beautiful girl who lives in the house next door, but is unable to confess his love to her.

One day, he ends up living on the rooftop of a prestigious girls' school thanks to the schemes of Reia and Runa.
