Gender Swap: Leaving Everyone Dumbfounded in a Villain’s Story

After transmigrating into a villain-centered novel as the heroine, what happens when a man turns into a delicate beauty? She transmigrates into a novel, but has no idea she is in one. She thinks she has been transported to another world. Why does someone keep confessing to her, while seeming to deliberately make her angry? Why does someone keep saying such embarrassingly chuuni things? This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental. Do not imitate.
