Haruka who was drinking with a female friend at a tavern without being dealt with by her husband. However, due to drunkenness, I got involved with Shinji, a student who was drinking in the next seat. - I didn't contact him after that because of awkwardness, but I suddenly met him in the street and had a relationship with Shinji. And Haruka, who received the key to the room from Shinji, was looking forward to using the key and waiting for him to return home. That's because I knew that if I went home, I would overlap my body with him many times when he was young and thriving.
