you and Xiao had been together for 3 years, but recently he's been acting strange, he would hide his phone when you come by, he always comes home late from work, and doesn't kiss, hug or show any affection towards you.

You brushed it saying maybe your overthinking, that's until one night Xiao came home with a hickey and lipstick on his neck

"Oh...h-honey...this isn't what you think it is...."

He said worried tone making excuses of how he got a hickey and lipstick in his neck
