!! MAJOR STORY SPOILERS !! im open to questions if anyone's curious about anything (im not a novel reader have just read almost all spoilers I can find
Spoiler!
Sh** gonna go downhill for awhile 😭 Gallico and San Carlo will be at war soon and while Alphonso is gone his knight and possibly Raphael interfere by getting rid of ari and Al's letters to each other so there was a big misunderstanding. While Al's at war ari is given a countess title and because of that, King Leo (Al and Ceasers Dad) proposes to Ari?.. last minute Ceaser comes in with guards and demands he marrys her instead and the king accepts so yes... they marry in this timeline but in the end ceasers a dog and cheats so they divorce.
I couldn't find anything specific about him finding out lucrenzia was unfaithful I'm thinking Ari keeps it to herself since her father trusts her and not her siblings
Spoiler text.she ends up with Al!! Currently as of now she's with Alponso!! He is endgame cuz now (currently) he's taller that Ceaser and more buff with longgg hair
