I feel like I'm gonna be the minority in this but' it seems unfair to the rest of his lovers as he has formed these bonds with each of them whereas the princesses love is strictly one sided I feel it wouldn't be fair to the lovers who forged these bonds with lux throu hardships only for a spoiled princess to force marriage onto him. plus it was already established that his lovers wouldn't allow any more to join his harem. I understand no wanting to reject her but I think it would be for the best as she only really has puppy love for him since he saved her' he himself has no particular romantic feelings for her. so to be in a loveless marriage I doubt would be fair to either one of them.
Take her, You built up Lux as someone that values friends and relationships, plus he isn’t good at rejecting women especially ones that put him in such a situation kinda like what happed wit Aurelia and Valerie. She would add some energy to the harem and some innocence that only Valerie had. Thanks for the chap and I have witnessed the marriage!
Let her be apart of the harem. But back of the line of course for the position of official wives. Obviously Iris and Cai are #1 and #2 as well as Ana being #3. The 2 dragons and bad-luck princess can be 4-7, this one will be 8 and the two hand maidens are concubines. I don’t think it’ll be a problem
