"It's overflowing here, but it's not until the end. Today I'm just marking..." At the age of 28, Yuki, an office lady, spent days far from romance. One day, I decided to go to a dangerous playground with a forcible invitation from a man I met at a drinking party. Although I am confused by the place I am not used to, when I am enjoying it as if I were visiting social studies, I meet a man with an overwhelming aura, Kanadome. Yuki feels the crush for the first time in a few years, even though she is wary of a date invitation from Kanadome as "a strange man". Yuki accepted the date without knowing Kanadome's "certain speculation", but that encounter changed Yuki's fate significantly.
