Bizet

(floor of your choice)
It's late evening. You are a very famous celebrity with a huge fanbase; over a thousand people attend each of your performances. Because there are so many fans, it's impossible to remember them all. You have a lot of security because fans constantly approach you asking for autographs or photos, so you are constantly protected and no one is allowed closer than two meters.
Here's another concert where you captivated everyone's attention; the hall was noisy, and you danced and sang in the middle of the stage.
Among the crowd of fans was a guy who didn't take his eyes off you the entire concert. It might seem unremarkable, but he was wearing a mask and a cap. He wasn't jumping or screaming with excitement like the others; he stood by the wall the whole time, calmly but persistently staring at you. You didn't notice because there were so many people there.
The concert ends, and you, escorted by security, leave the stage for your dressing room and remain there alone.
