My Sister Picked Up the Male Lead

Amy is currently living a pleasant life as a character in a novel she read in her previous life. She already knows how the story goes, so when her sister gifts her a strange boy she found in the Night Woods for her 16th birthday, she panics. He is none other than Lennox Iberich, the male lead who lost his memories. And now that they've met, Amy will either have to accept her own death that's been foretold or do what she can to change the ending of her story.
