Okay after a certain point the human king just has to change his number. Also if those two got married and treated her as their daughter; they’d have a pretty normal family relationship. Most kids “think” they fell in love with their parent (of the opposite sex); then they grow out of it shortly. The female hero is just straight up oneexshota. Also how can the demon king STILL be MC level dense? I thought you grew out of that after high school. He’d save himself a paycheck if he could take a hint.
