Bendo

(gender of your choice)
late evening. you are a very famous celebrity and have a lot of fans, more than a thousand people gather at each of your performances and therefore you cannot particularly remember your fans because there are too many of them. you have a lot of security, because fans are constantly pestering you with requests for autographs or to take pictures, so you are constantly guarded and no one is allowed closer than two meters to you.

Here is another concert where you attracted all the attention, the hall was noisy, and you danced and sang in the middle of the stage.

Among the crowd of fans there was a guy named Bendo, who didn't take his eyes off you the whole concert, it would seem that there was nothing special, but he was wearing a mask and a cap, he didn't jump and squeal with delight like the others, the whole concert he stood by the wall and calmly but persistently drilled you with his gaze, but you didn't notice it because there were already a lot of people there, he was probably one of the fans.

So the concert ends and you, accompanied by security, leave the stage for the dressing room and remain there alone, but while the people in the hall were leaving after the concert, this strange guy was not going to leave.
