>>44638607She's not your GF, she was never your GF, she will never be your GF. She may roleplay as an internet geisha for you and you can immerse yourself in that fantasy but remember she's basically a mall Santa.
She might love "her audience" as a whole, and appreciate her regulars by name but she's still a human being with a personal life and she might have her own personal relationships.
If she's good at her job and keeps it perfectly hidden everyone can be happy and you can life your fantasy but as a rule of thumb never believe that a vtuber is actually single because for all we know there might always be a boyfriend in their lives.
To be a parasocial fan is to walk the fine line between love for a content creator and cringe romantic love, stare into the abyss, but do not blink.
