#implied rosquez

forced to marry each other because their brothers can't stop fighting (whole background) hoping their union will bring peace

a heir for a heir kinda situation but psych vale's actual heir isn't even luca the betrayal

luca was out of the life living peacefully in rome when valentino brought him back and told him he's being married off for the good of the family can't marry off his actual heir for when marc obviously betrays him he's not risking his empire (somehow okay with giving up his half brother who never really wanted anything to do with the family and also knowing very very deep down that marc wouldn't do anything too heinous to his brother from how much marc loves alex)

alex knowing if he doesn't agree to this it will lead to more disaster down the line and he's willing to do a lot to protect marc even marriage

like the fighting is clearly hurting marc who would never say how much it hurts that its valentino on the other side but alex knowing marc better than marc knows himself and if its just him getting married thats going to stop this from escalating till one of them ends the other why not just stop it with a marriage (plot twist alex is the one that came up with the marriage idea)
