Shuji, a freeter who is semi-cohabiting with his girlfriend, doesn't understand women's hearts and is always fighting with her... He was consulting Yuki, a senior at his part-time job, about his love life. Yuki, who was listening to that, seduced Shuji, got him drunk, and had sex with him. Since then, the two of them have been repeating erotic things during their part-time jobs. However, Shuji felt guilty towards her.
