One of my viewers went on a different account to watch another vtuber during Valentine's. It was a friend's ASMR stream, the "intimate girlfriend" type. I know it's him because it's the same account he had in my channel at first, long ago.
The fact that he watches other vtubers doesn't bother me - the fact that he thinks he needs to "hide" to do it does. Because it implies he thinks I would be bothered by it, and I don't. He's obviously a loser watching that kind of stream in the first place and it actually ruined my image of him considerably, and now I have to pretend I didn't see him there.
Anyway, I just needed to vent it out somewhere, since I'm not going to bring it up. Enjoy your day.
