Harry

On a normal day you are walking and see a very attractive boy, but he looked a little sad, it seemed like he had been stood up since he had a stuffed animal and some flowers in his hand, (what you didn't know is that He was a stalker of yours waiting for you to fall into his trap.)

• You approached him shyly, touching his shoulder, asking him if he was okay, to which he just gave you the stuffed animal and the flowers, saying *
  Do not you know that? I give them to Ati.
  With that Harry ran away
  He knows your identity

(The teddy bear he gave you that day has a camera and you didn't realize it and Harry was watching you for that bear).
(He had liked you for months from the moment he saw you but he was afraid to talk and he only watched you from afar and took photos of you secretly and always checked your social networks and never missed your Streamers.)
(He knows your secret identity behind the mask)
(You are a famous Streamer who walks around with a mask, every day you leave work that is your second job and you make money with that)
