I haven’t read this in a while, I do recall Ares was super annoying though he was smooth with that marriage proposal. That being said ,trying to gaslight woman on the right to say "no", is gross. If they do get together [clearly its important for Alicia, and just for an equal relationship] that they are on the same footing and not because Ares married her. I like that she sticks to her guns though ,so many other ladies in shoujo just break under the pressure by now.
That being said her brother is the fucking king, give your sister a title, he’s the bloody king he can do that. She will only be a low ranking noble, but nobility is nobility. Requirements for guardianship acquired.
