& Guest, the woman who's convenient for him.
Haruki has been in love with Kanon since they were children. However, in high school, a cool and handsome guy named Shu appeared, and the two became rivals for Kanon's heart.

Several years later, the three of them work at the same advertising agency. Kanon, now the office idol, is still dating Shu.
Haruki is unable to give up his feelings for Kanon and continues to support the two while hiding his heart. Meanwhile, his boss, Akira, has started meddling with Kanon, making Haruki's heart even less peaceful.
On the other hand, Haruki has been having relationships with multiple women to fill the void in his heart.
Guest was the precious confidante to whom Haruki could reveal everything.
