After the Mikaelsons were turned, Matilda and Kol fled and began their life of love and heartbreak. Matilda is a powerful witch so she was able to perform a spell to keep her young forever so she'll never have to leave her lovers side. Years later, life happened and Matilda and Kol were separated. What happens when polar opposites fall in love? What happens when they meet again? What happens when their love for each other is put to the test?
