A love story spun by a "sulky novelist" and a "college girl who wants to be in love" - under one roof, with a 10-year age difference! Shion Tachibana, a novelist, is busy with her writing, but her days are peaceful. One day, Rio Hanaoka, the grandson of her landlord, comes to Tokyo to go to college and suddenly moves in with her. Shion, who is reluctant to be in love, and Rio, who has never had a boyfriend in her life and whose goal is to "fall in love," are complete opposites in terms of values and personalities, and fight as soon as they meet. Will the day ever come when their clumsy feelings will be able to meet?
