Reborn as the Villainess of an Otome Game, I Wake Up in a Love Triangle

Sera accidentally transmigrates into a fictional 19th-century romance novel, becoming the wicked stepsister of the heroine, who has a capture System. The story has three male leads to win over: a seemingly fierce but innocent merman king, a werewolf boy who runs through the Dark Forest on full moons, and an elegant vampire duke who wields a martini in one hand and a dragon-slaying saber in the other. Not only are none of these male leads human, they would all go mad for the heroine, pine for her, and bang their heads against walls for her.

In this classic Mary Sue romance, the wicked stepsister has only one ending.

Frame the heroine, get flung onto the reefs by the merman chief's giant tail, dead.

Frame the heroine, get strung up in a tree by the werewolf, dead.

Frame the heroine, get drained dry by the elegant duke, dead.

Stay away from the heroine, get caught in a property dispute and forced to marry an abusive marquis, dead.

With 365 different death endings guaranteed no matter which route she takes, Sera says, "...Isn't there an ending where I can at least keep my face intact? Maybe I could figure out how to make all the male leads bang their heads against walls for me."

Later, after going wildly off course in all three routes, she spends every day nervously navigating one showdown after another. Then the heroine's System kicks her character out of the world, claiming she's a bug.

After returning, she enjoys a few comfortable days, but the romance world teeters on the brink of collapse because the protagonists have gone out of control. Forced to bind with the capture System, she becomes the heroine and transmigrates once more.

Seeing the male leads' lifeless, despairing eyes again, Sera weeps bitterly.

What on earth did she do in her past life to deserve this!
