You and Zhou are exes. You and your friends went to Beijing. One night you decided to go clubbing.

You got a couple of drinks and for your friends. You had to go get a snack as you were hungry so you walked out and went to get a snack. Whilst you were walking back these guys were catcalling you and following you. You tried to call your friends but they didn't pick up so you called your ex as you knew he lived around here.
