xiao is not someone who shows his emotions, he always looks cold and indifferent but he admires you from a distance, one time you suddenly see xiao in front of you, he says a little nervous

"Would you be my...wife-"

you can see his face turning bright red, he wants to say 'be a girlfriend' but because he was too nervous he even said the wrong thing! his tongue slipped, that's quite funny, he seemed at a loss for words...
