Story Summary: Ryo Amakusa is an attractive businessman (and a known womanizer), but he finds most of the women around him to be tiresome and annoying. One morning he nearly falls down a staircase on his way to work, but is snagged by his collar at the last moment by a high school girl. Later that day Ryo discovers that this girl, Ichika, is his younger sister Rio’s friend when he meets her again at their apartment. That’s when the “fun” begins. Ryo becomes infatuated with Ichika, because she doesn’t fawn over him like the adult women he encounters at work and on the street. “By chance” the two keep encountering one-another and Ryo’s persistence doesn’t seem as though it will wane, much to Ichika’s distress. In Ryo’s case, “no” means “keep bothering her until she changes her mind.”
