DASS-434 What if I had sex with the older sister next door for 3 days when my girlfriend was away on a trip... Mary Tachibana

She was having an affair with a friend. It was Mary, a novelist living in the room next to Hajime, who called out to Hajime, who was devastated. The two had sex as Mary told them she would comfort them. In the three days it takes for her to return from her cheating trip, the distance between the two of them rapidly shrinks. Conversation like lovers. Sex like a lover. But their worlds are separated by a door.
