Twenty-three-year-old Hina currently lives with her boyfriend Teppei. Although the two are deeply in love, there is one thing that they have clashing opinions on: baths.

This prompts him to devise various strategies that always end with his stubborn girlfriend in the bathtub alongside him, creating sweet and bubbly memories for both of them.
