Becoming the Only Memory of the Male Lead

The body was possessed before the start of the novel.
Also, she, the daughter of a Count, is an extra who is bound to be murdered.
She didn’t want to die like this, so she went in search of the male lead who’s filled with the energy of life.
The problem is that, due to his curse, he can’t remember others.
As the next best solution, she even tried to target his subordinates.
“It’s been long, Loreina.”
What? Why does this person remember me?
It was unexpectedly due to an exception of the curse.
Um. Well, I’ll help you until the female lead appears.
The only one who can break the curse is the female lead, so that it doesn’t deviate from the original story.
…Yeah, that’s exactly what she thought.

Kiss.
I felt a soft touch on my cheek along with an unfamiliar sound. A tiny kiss landed on my cheek.
“…Le-Leonard.”
“Stay still. It’s interfering with the treatment.”
“No, but that’s…”
I understand that you’re healing the injured area with the energy of life.
“Is there any other way than this? You can just touch the injured area with your hand…”
“No.”
Leonard just cut me off.
…No, there’s no such thing!
