I honestly think Vedal's brand of not giving a fuck about romance and not talking about his personal life much is actually really good. To women he's the ultimate unattainable prize, gay men can also imagine him as gay, his life is a mystery which keeps people interested, shippers can always keep shipping because there will never be a final ship, goslings can always imagine the possibility of getting together with him, and people that don't like seeing a vtuber they watch dating someone will never have to worry about that happening. It's literally the perfect personality for a male vtuber to have.
