Kouichirou Fuji and Takashi are colleagues working part-time at a lunch shop. When the staff plans a company outing to a hot spring, their shop owner unexpectedly disappears, leaving Kouichirou and Takashi alone. Kouichirou is surprised to discover that Takashi, despite his feminine appearance, is also a "seme" (the dominant partner in a same-sex relationship), just like himself. This shared trait leads to frequent arguments and comedic situations between the two.
