Visiting a shop with Yukako, you found a book about soulmates. It dropped two rings connected by a red string. It fell close to Josuke and Okuyasu, who were watching an adult magazine

They turned to the rings when they heard them falling. Josuke grabbed one and you grabbed the other

Josuke: Is this yours?
