WTF I've been reading this to find out that this is ANKAMA'S WORK!!?? lol I've played Wakfu and seen the anime and now THIS??? I feel a bit betrayed to just find out that this connected to Wakfu. BAHAHAH... now im expecting to see tie ins from wakfu's anime now.
Honestly it would make an interesting plot if he was gay or bi even. There's just too many stories even for isekais where a woman slave or otherwise meets a royal man... These authors make their female leads soooo sacchrine or sooooo relatable and pair them off with some douche royal to be king?
It's clear shes gonna be his fiance but i'd rather her make him suffer in exchange (and definitely not fall in love so melodramatically)...
tl;dr Once you've read one, you've read them all, i'm not expecting much.
