The Yellow-Haired Villain in the Female Main Character's Novel Wants Happiness

Transmigrating into the body of a blonde-haired villain at the start of a yuri novel, Mu En just wanted to survive. But… why does the story seem to be going off track? The princess is drugged and unclothed — so why hasn't the heroine shown up to save her yet? Why does the heroine’s childhood friend, a noble and pure saint, keep giving me flirtatious looks? Even my obedient personal maid has started looking at me in alarming ways! Where is the heroine?! Please save me!! "If you're going steal my women, you better be prepared to take responsibility…" the protagonist told me, with a kind smile on her face and a sharp machete in her hand. (Source: SFACG, translated)
