I love that Alexis is forward. Most of the paying fans do, as well. She has been consistently at the top (usually #1) of the polls from the very beginning.
Right now, Valeria has taken more than a 200-person hit on her likability. That is to say, 200 fewer people are voting for her as their favorite character on Patreon. You could argue that her agreeing to go out with Darryl (or anyone other than the MC) was out of character. While I think the older, more mature audience would support that claim, the unfortunate reality is that the masses are just mad that she would go after anyone other than the MC.
So, while there will always be people who complain that not every woman should drop her panties for the MC, in reality, it is wiser to not introduce competition for love interests if you want to keep young minds happy. It creates a predictable, less dynamic, and somewhat boring story. But it also keeps kids from losing their damn minds.
