You were paired up by your boss with a man names Xiao. He was always so serious and cold, like probably he never chill when he's his job, probably not even for a second. Laugh or smile is very rare in him but because he's an attractive and handsome man women and girls show him often attention on streets.

One day he came to you, with his always serious and cold expression. His voice was quite deep and attractive.

"Come on, we have a mission"
