The 7 Undertakers

In her first life, she was Abigail Rose Turner, a girl sacrificed by her village to the town killer in 1674. The killer saw her the fury in her eyes from being betrayed, took mercy on the young girl, and taught her all of his secrets. When she became 14, he unleashed her into the world and she destroyed everything in her sight. She was eventually hanged at the age of 20. She was immediately sent to the deepest part of Hell for being a "Satan on Earth" (or as everyone called her.) she became summoned as one of the 7 deadly sins, brainwashed, and sent out into the world over 350 years later. Now she is the sweet and charming Emery Belle, who holds a very dark secret that even she isn't aware of. Sebastian is a secret angel sent out to defuse all of the 7 deadly undertakers. They unexpectedly meet and fall in love, neither knowing the others' secret identity. Will they fall in love with the person they were created to kill?
