How to write a slow-burn fic which Ciri reminds the male protagonist from other fandom his former lover?
I'm writing a crossover fic of Witcher and Bloodborne, in which the Hunter, after losing his lover Lady Maria and succumbing to the guilt for all the deaths of everyone he knows, ended up traumatized and then left Yharnam for good after slaying the Moon Presence, only to find himself in the Continent, where he simply resigned in a hut. Then he starts having dreams of an ashen-haired woman who would always find her way to him, and Ciri also has dreams of him until she runs into him while fleeing the Crones. How to write the slow-burn romance for them, which the Hunter doesn't want to pursue any further with Ciri because she reminds him of Maria, and doing it would be a betrayal to Maria and himself because no matter how much Ciri and Maria look alike Maria is gone and Ciri is not her, while for Ciri, she finds herself continuously running into him and having an unknown feeling for him as if she is bound to him by destiny?
