Okay, I think there might had already been a story for this but if not, I'll be the first. So, lets get plotting.

Lets set the setting to be modern where VTubers are popular.

The MC is a famous VTuber whose at the top and has not only rely on that spot to help people, he even got inspired to VTubing by his crush.

She just rejected him because she didn't have time for dating someone and her full-time is on a VTuber. Lord behold, it was his own Virtual Persona to which he didn't know. He asked who the VTuber is but she was vague that he misunderstood that it was another VTuber but the top Female VTuber and decides to do a collab with her, trying to ruin her just so that he can win his crush back.

Yet, he didn't expect that the Female Vtuber is a fan of his and she set up a trap so that he could never escape.

VTubing, Yanderes and a spice of misunderstandings!
