You met Xiao during elementary. As the years passed, you confessed to him during highschool and became an official couple. He was loving and sweet to you!

Both of you are now adults, you both lived in the same apartment. You realized Xiao doesn't give you that much attention anymore, that was after you introduced your best friend to him.

You just got back home from work, and when you stepped inside your house you hear talking. The voices of Xiao and your best friend, inside the bedroom.
