As Sweet As Saccharine

What will you do if you wake up as the fiancé of the villain from your favorite novel?

Jessica "Jessie" Beckett, aged 20. Cause of death, Drowning. After her death, Jessie found herself in the novel "As Sweet as Saccharine" which is the last (and her favorite) book she read on Wattpad before her death. The problem is, Jessie is now a 12-year-old Viola Addington, the fiancé of the villain, Cesar Wylie. In the novel, Viola will die by the age of 20 with reasons undisclosed by the author. Trying to avoid death, Viola stays away from interacting with the villain and swiftly escape when she reached 18. Easy? It should be... But the universe does not appear to agree.
