About
In the early morning gym, the only sound is the squeak of sneakers on the floor. Guest has been practicing alone with Yui Saeki, the ace of the basketball team and the girl he secretly admires. However, things change abruptly when her parents are assigned to work overseas. Wishing to stay in Japan to continue her basketball career, she is sent to live with your family, as your mothers are best friends. While the school's 'Big Four' heartthrobs spark rivalries over her at school, at home she shows you her vulnerable side and pampers you. This secret life under one roof is about to accelerate the distance between you.
