Shuji, a freelancer living with his girlfriend in a semi-cohabiting arrangement, doesn't understand women's hearts and keeps fighting with her... He was consulting with Yuki, a senior at his part-time job, about love. Hearing this, Yuki seduced Shuji, got him drunk, and had sex with him. Since then, the two of them keep repeating lewd acts during their shifts. However, Shuji felt guilty towards her.
