A dull salaryman, Yoshino, lives quietly in a suburban apartment. One day, a flashy gal with a delinquent style, Riri, moves into the neighboring room. Initially thinking she was a troublesome neighbor, Yoshino had been deliberately avoiding Riri. One day, after he helped her deal with a cockroach in her room and saved her from screaming, the distance between the two quickly closed. "... "I'll make it up to you for all the kindness" she said, and entered Yoshino's room. Riri started coming over frequently, acting cold but taking care of Yoshino, sometimes even acting spoiled. When Yoshino couldn't resist this gap anymore, Riri opened her pussy.
