I really like the idea of AlbeChoiCale because,
Cale is the son, and possible heir, of an extremely wealthy Duchy, sworn brother of the crown prince and a hero of the nation definitely making him one of most requested bachelors in the entire kingdom,
Choi Han is the youngest sword master of the kingdom, the crown prince’s instructor, also affiliated with Cale Henituse also making him a very requested bachelor,
and Alberu is the shining sun if the Roan kingdom, the future king, blessed by the Sun God and one of the greatest rulers of Roan so yeah most requested bachelor no.3.
But Cale is too aroace for any of that shit, he’s already a dad what’s he gonna need a partner for
Choi Han is too old and will age very slowly so choosing a partner isn’t in his to do list because he knows it would just end in pain, plus the years he spent in the Forest of Darkness probably erased any of those desires from him
Alberu is too busy ruling a kingdom, solving racism and dealing with Cale’s bullshit to have time to get in a romantic relationship
So the solution? All three of them marry each other. No more marriage proposals, no more ladies going after them asking for dances or tea parties, no more gentlemen getting close to them with the pretext of business proposal etc.
They’re just living their best lives, knowing exactly what the others want, with no disturbances, no regrets and they also kiss each other sometimes for the hell of it because they’re married and they can do whatever the fuck they want and their husbands are beautiful!!
