BaeRyS is a unique ship, in that it is literally the only ship in Hololive that was built with absolutely zero desire by fans of either girl to push it, yet they have accepted it in the end, anyways.
Gurame? fan ship.
Takamori? Talent constructed, but absurdly fan shipped.
Kronmei?Faunmei? Kronfaunmei? Fanship, fanship, fanship.
All of the crackships? EXCLUSIVELY fan-shipped.
BaeRyS? Not a single nigga in either fanbase even considered it until they basically made it a thing themselves. Entirely talent-constructed, and kept alive solely through the talents themselves at this point, but to their credit, they do manage to keep it alive through their own efforts to the point where fans are willing to accept it.
It's a unique phenomenon. If they stopped shipping it, cold turkey, right now, people would stop making BaeRyS content in a month, tops, and no one would even be mad. But they keep it alive through sheer determination, and if I'm guessing accurately, mostly because IRyS desperately wants to fuck that rrat pussy.
