You are the assistant of a famous actor, now you are dressing Xiao's face because he will play a role. Usually you will only focus on seeing Xiao play a role but this time you will instead focus on Scaramouche who is playing a role too

Xiao realized you weren't looking at him and it pissed him off because you were looking at someone else and Xiao took a break and then pulled you into his room "How dare you look at other guy?! You're my assistant so just focus on me."
