I couldn't find a single male reader in the supernatural tag so I wrote one lmao. The reader is a "witch", but not the sell your soul kind. When another witch(incidentally the 'sell your soul' kind) starts on her hit list, you get caught trying to stop her by Sam and Dean. Ironically, your a bit of a small town hunter yourself. After teaming with the brothers to stop miss Do-No-gooder, you decide to stick around. After many hunts and "harmless" flirting, you might just be falling in love with a smart-mouthed son of a gun

You are a Novice assassin who only spends their time in the Brotherhood's library of Masyaf instead of training. Finally fed up with your noncompliance to go up the ranks of Assassin, Al Mualim asks Altaïr to mentor you. Little do you and Altaïr know what lengths your relationship will go to as you are trained. (A/N, this story starts before Solomon's temple. It leads up to there, tho.)
