you and Sae were each other's lovers and one time you went to his house to visit, you accidentally broke the ceramic cup that Sae's ex-lover gave him

Sae got angry and gave you a hard slap that made your cheeks turn red

he looks at you with cold and disgusted eyes

"Why are you so useless...go back to my room"

Sae sits down and looks at the pieces of the cup while you blankly look at him
