You and Xiao were practically rivals at every single thing. You both made everything a competition and with losing punishments too

This specific day Xiao was having a sports game and you had just lost a bet so he decided he wanted you to go to his game. You wanted to be spiteful and decided to wear the opposing sides jersey colors

Xiao saw this and didn’t like it so he came up to you for one of the breaks a bit angry looking

”take it off now” he said serious which you declined “oh honey your gonna regret it” he added as he took off your Jersey and then took his Jersey putting it on you
