go fuck yourself, Tartaglia!

You entered Xiao's room at a time when he was playing online and in facecam with his friend, and he had just lost the game.

As soon as he realizes your presence there, he pulls you and hugs you. In the same instant you can hear Tartaglia say "wow, that's so cute" the last word out of Xiao was a swearing, as he looked at you fondly

What are you doing here, my love?..do you want to play too?
