Like at it's core WHB (along with any other interactive romance/relationship based game) is an escapist fantasy for people to indulge in an idealised relationship without the risk of facing betrayal the way you would in an IRL relationship.
The whole appeal of characters like Lucifer and Leviathan (and, to a degree, Satan) is that they make you feel special. You get to indulge in the fantasy of being the only one able to get them to open up, the only one they're that close to, and the only one they want to be with. You get to play out the role of being special enough and valuable enough to gain the trust and intimacy of someone who's otherwise very closed off, and defensive, and who doesn't let their guard down easily.
So to build up that fantasy of being the only one that matters, being special and different, and having worked for their trust and intimacy and the privilege of being the only one who gets to have them like that, and to then haphazardly throw out an event where those characters very openly fuck other people knowing full well that whilst certain fans are into that, the target audience they're pushing it towards (Luci, Levi and Satan fans) typically do not enjoy it, feels like such a slap in the face.
It's not just bean soup mentality. ("it's a kink event in the kink game, but I don't like that specific kink!") It completely crumbles the fantasy it's built up to appeal to the audience in the first place. It doesn't just add in something people personally dislike like some of the other kink events, it actively takes everything that made it likeable for some fans and crushes it entirely.
They took the "you're the only one I want" characters and then made them want literally everyone else on a random Tuesday. And it's particularly hurtful because there are several other characters they could have used that this would have worked for. There are fans who do enjoy this kind of thing. Me included! But they weren't marketing it towards those fans, they're marketing it towards the fans that want it the absolute least. And they're completely fucking up the appeal that drew those fans in to begin with.
