The Devil Falls in Love

Looks like Karin is at it again to get Sasuke to fall madly in love with her. But what if it back fires? What if a potion given to her by Kabuto gets in the wrong hands and a certain blood thirsty boy takes it? What the heck happens then? Poor Karin! She might not get her Romeo but someone else might get their Juliet... Challenge accepted to Dotchi13
