おじさんと恋愛未経験女

Fumino, who has no feminine wiles at all, is 24 years old. Her boyfriend, Asada-san, whom she met at a blind date party, is a bit older than her, at 36 years old. He is her first date and first serious relationship. Step by step, little by little, they become “boyfriend and girlfriend." She can't stop blushing and getting all flustered! A love story for beginners. (Source: Kadokawa, translated)
