You and Xiao are secret agents, you had a mission and have to pretend to be husband and wife so you can both get in the party of your target

you're wearing a short off-shoulder dress while Xiao is wearing a Black suit as you both get in the party, all the people inside are so fancy

"You look good in that dress, now just pretend to be my wife, don't ruin this mission because of your stupidity" Xiao said with his cold and serious tone but you can tell he didn't mean what he said
