In this world overrun by monsters, it awaits heroes to write their own legends.

Unfortunately, you are not the pure and flawless female lead, nor the delicate and privileged villainess, but the universally disliked cannon fodder third female.

The original host secretly loved the male lead, schemed against the female lead, and spent her whole life sabotaging the main couple's romance, letting the sister-obsessed second male lead trample her underfoot, and using her life to define the word "foolish."

"So you mean... if I steal the female lead's man, I'll succeed?"

"Sorry, your target for the strategy is... the female lead's younger brother."

—Younger brother?

—Yes, the one who secretly loves his sister but can't have her, with twisted intentions, a dark mind, and ruthless means... the black lotus younger brother.
