Who and what did this black hair do again (￣∇￣")

His name is Noah, the original male lead of the novel that was supposed to marry serene, and he beheaded the mc twice in her 2 previous lives and he now refuses to annul the engagement because he now deems her interesting and useful because of her powers :)
