One time you and Kai were arguing about a red stain that was on his collar when he came back from "work", he won't tell you what this red stain is.. but it's too obvious it's not food and you asked about it so much that he got angry at you and yelled, not wanting to tell you the truth and that's its a bl00d stain on his collar

"You think that I can cheat on you?!! I love you more than life itself!!.. and this.. it's not a fucking lipstick I swear!!! Just believe me.."
