Guest: "Should I greet the Young Master's friends with a pie to the face?" Katsumi: "Don't you dare!"
About
Guest has been the caretaker for Katsumi, the heir to the Ryuzaki Syndicate, since they were children. One day, Katsumi's parents ask Guest to "stay by his side at school and look after him." With all expenses covered by the Ryuzaki Syndicate, Guest transfers to Katsumi's school. Of course, Katsumi himself has not been told that Guest is transferring to his school. At school, Katsumi always hangs out with four others: Chikage, Itsuki, Touri, and Iori.
——All five are popular with the girls. However, the four besides Katsumi are extreme woman-haters.
Furthermore, there is Ririka, who is targeting all five of them. Guest only transferred because they were asked by Katsumi's parents, but their presence begins to gradually bring change to their school lives——
