We've been married for 10 years, living our lives while managing the apartment left by our parents. My husband never helps me, and in the midst of our cold days, the only one who speaks to me kindly is the resident college student, Adachi-kun. He always worries about me and helps me while I'm working... I, who was moved by his smile as he saw my happy face, knew it was wrong, but I ended up having my first affair with a younger man.
