A Forced-Romance Novel's Female Side Character? The Crazy Male Leads Are Turning It into a Battlefield

[Noble academy + domineering possessiveness + multiple male leads + everyone is a villain + everyone's darling + Mary Sue + men competing for the heroine]

(Male leads: domineering, rebellious childhood friend; crazy, flirtatious heir to a powerful family; older, paternal, abstinent man in control; sweet-faced, black-hearted, lovesick puppy; impoverished, aloof senior...)

Qi Wanli is reborn and discovers she's the vicious supporting female character in a coercive romance novel, the biggest obstacle on the protagonists' path to happiness. Controlled by the plot, she falls deeply in love with the male lead and does everything she can to ruin things for him. Once the protagonists reach their happy ending, she's cruelly written out of the story.

After being reborn, she plans to stay away from them, but gets bound to a System. Qi Wanli intends to complete its missions and then flee far away. So why have they all gone dark...?

Notes:

1. All male leads are virgins.

2. Brace yourself for melodrama. Neither the male nor female leads are good people. The heroine is a scoundrel and a little crazy too, willing to use anything, including herself, to get what she wants.

3. Brace yourself for melodrama. The heroine is weak, and there's a huge status gap between her and the male leads. She's not a strong heroine. The whole story revolves around coercive possessiveness, so think twice if that's not your thing.

4. The heroine will turn dark later on, but only take the lead in the romantic relationships. Specifically, the male leads love her, but she doesn't love them, and the male leads go dark.

5. The heroine has an idealized first love, with a forced-separation trope.
