I don't understand the point of a "faithful route" with Millie, seeing how you CAN'T avoid having her rocking your socks off with a blowie and a dream intercourse in the first place, and the "faithful" choice comes after you already fucked her brains out which the angel scolds you for and prompts you to reverse time so that it never happened.
Granted, the choice came from the Patreon supporters to not cuck the lovable imp husband man, but ultimately it just seems like a weird compromise that satisfied nobody with how you went about it. Not to mention, making all future Millie scenes essentially dead in the water so as to not cheat on Moxxie.
If there's gonna be that many restrictions when making the MC an OC, why not just make Moxxie the POV character then? Surely no one's gonna object to a harem started by him. Otherwise, stop it with the compromise, either you have an affair with Millie or you don't and not split it into a route with Loona.
