Instinctual Love(Scarian)

(not my art! found it off of google lol. whoever's art this is, it's amazing!)
Grian is part vampire. Scar is a vex, and when bitten, they must bite back, to create a mate bond with the other. Well, the avian/vampire ran out of blood, and was starving. He lost control, biting Scar. Which sent Scar into his mating instincts, so the vex bites him back. They now have to figure what to do now that they were unintentionally mated to each other for the next year and had somehow fallen in love in the short weeks they had known each other.
