Rina comes to Tokyo to rely on her older sister Maya, who is married and lives in Tokyo, and lives as a freeloader at her older sister's house. She turns a blind eye to her sisters who are excited about her new boyfriend, and her husband can't help but worry because he is responsible for taking care of her daughter who is around her age. Despite these worries, Saeki, who dutifully came to greet Rina while dropping her off on her way home from a date, is a friendly man. However, although this man is serious on the outside, he actually likes women. section
