Oraku seems to have a fortunate life with a cozy teaching job at a nearby high school, and the love and respect of Satsuki, a fellow teacher, and Aya, a beautiful student. However, his life is plagued by various complications. Aya's wealthy father is a notorious gang leader who will harm Oraku if Aya is not chaste. Moreover, Aya constantly tempts Oraku by lounging half-naked in his living space, making it challenging for him to maintain his boundaries and shield her from inappropriate advances from others. If his colleagues or anyone else discovers his living arrangement with Aya, there is a risk of permanent expulsion from teaching. All in all, Oraku's life may look splendid, but the circumstances he faces are far from favorable.
