I can't believe I'm the one saying it, as I am usually pretty chill about this stuff in comedic fantasy settings, but aren't the hero's actions a bit problematic? He locked her down, cut all of her ties with her friends and subordinates, he's controlling and domineering, he's clearly much more powerful than her and is easily able to suppress any escape or fight attempts... The fact that he's "doting" and "kind" and "infatuated" doesn't make it okay...
