The protagonist’s childhood friend Fuyuka came from a rich family and was neat and pretty, so she was like the idol of the class. All the boys admired her, but they also found it hard to get close to her. He felt the same way as he had liked her since they were small. Maybe she was his first love. However, they grew distant from one another after they went to separate schools.
One day while returning from Akihabara, he was mistaken for a train molester. The victim was Fuyuka, who he hadn’t seen for a long time. Even though it was just a misunderstanding, she told him that if he wanted her to forgive him, he’ll have to become her butler.
