The Final Villain Has Fallen to the L**t Demon

“Touching you seems to make it better. Can I do more?”
I possessed a short-lived extra in a 19+ novel that was discontinued mid-serialization.
Specifically, I became Levi Heron, the daughter of a sickly knight family who possessed the special ability to suppress demonic energy.
According to the original plot, Levi was destined to die while trying to suppress a rebellion. A rebellion staged by the First Prince, Demian—the final villain and the virile sub-male lead who lost the competition for the crown—to coincide with an outbreak of demons.
‘But there’s still time before that rebellion happens, so I can change the future.’
So, Levi saved the original female lead from her miserable life and cleanly tidied up her past one-sided crush on the original male lead, the Second Prince, Frid.
With the help of the original female lead, her sickly body was slowly recovering. Now, all she had to do was quietly stay neutral until the competition for the crown ended, but……
“A demon has appeared! Prepare yourselves!”
“You can’t handle this with your strength. Get back…… Ugh!”
Against a suddenly appearing demon—and a le*d Lust Demon at that—she fought alongside Demian, the First Prince destined to start the rebellion.
In the process of trying to calm his demonic energy, the catastrophe of spending a night with him occurred.
