Well, first of all I decided to follow the love path of Luna, Garcie and Isabell. If the MC has to work for this family under contract, then he should have fun (and I should too). He is already training with Elektra and Eiza for the future.
I am well aware that this path is a dead end and it will cause problems at a certain point in the game, to say the least. For me, I have decided that if the case arises, then I will cheat. I know that's not what the developer intended, but I just can't decide on one of the girls at this point. Honestly, I want all three. I hope the conflict comes very late!
