Grah! At least call out your fans and the company for putting pressure on you to either leave or lie about your personal life. At this point, there're no more consequences for lashing out. Call out the shitty human beings that would call themselves fans, but send hate-mail when they learn that their supposed idol has a romantic relationship, because it would mean that they no longer have a shot at being with her when they'd never have one in the first place.
This whole thing reminds me of that one VTuber that lost a bunch of subscribers because a glitch caused their face to be exposed for a few seconds and people realized that the actor/VTuber was a man. Like what were you expecting? That the cartoonesque interpretation of a human girl was actually real, and now that you know they're not you're out? Absolutely delusional.
The fact that it getting out you're in a romantic relationship means you'll lose a significant portion of your 'fans' to the extent you'll have to quit really exposes how warped the whole thing really is.
