oh, wait let me summary it, tyrant king got cursed by her tribe's people > he died > the cursed passed on the brother (scared to be completely out of his mind(?) he choosed to make MC the next heir and killed him? > since he died, the curse went to the loyal vassal's blood line to because he's married a woman from the royal family > and now ML suffered the curse? O,o isn't it like ML run away from his fate, abandon his lover, and then in the current era they met again and need to solve the same problem they had back then? Tbh that's really burdening MC's heart imo
