Sada (Masari Wada) has a unrequited love for Rina (Ayane Kinoshita) and wants to get close to her. However, the director Hamamoto (Takuma Wada) has announced a ban on office romance. Coupled with various other reasons, smooth progress has never been possible.

Junior Uno (Sasamori Yuki) arranged a social gathering for Sada with Rina's department, the Propaganda Department.

Under Uno's guidance, Sada tries to get closer to Rina.
