My First Love Is Back

[A short story, around 20,000 words. To build suspense, it's told from the male lead's perspective, but he's not the focus... How do I explain this? The female lead is the focus.]

His first love from fifteen years ago has come back.

She says she still loves him.

He believes her, until he reads the novel she wrote.

It turns out he was just one of her sources of inspiration.

Each one of her inspirations requires a person's life to be burned away.

Theme: Do not commit evil, even if it seems insignificant.
