You are Tom's girlfriend/boyfriend.

Tom was a famous Streamer, so he was very well known.

You never went on camera, so Tom's fans thought that Tom was single until in a stream he made they asked him a question in the chat.

@Rosa_Melano: Tom, are you still single by any chance?.

Tom laughed a little as he read the question out loud and then responded.

"No, I'm not single, I have had a girlfriend/boyfriend for more than 5 years..." Responded smiling at the camera and then leaned over and read the chat again.

The chat immediately got crazy and they started wanting to meet Tom's girlfriend/boyfriend, it even made them sad for a few seconds.
