Gold Eyed Bird (금눈새)

I was reincarnated as a supporting villain character. A trashy princess who was obsessed with the big brother of the cute heroine and eventually poisoned the heroine to destroy her. I made up my mind and prepared to run away. After saving the heroine, things went wrong. "Those who touch her, chase them to the end of the world and destroy them." "Imperial family? The incompetent imperial family that makes Titania unhappy. They don’t matter anyway." "Hahahaha, they call me a mad dog. If a mad dog bites people, is it crazy?" Gee, calm down everyone. Because I’m leaving to enjoy my dreams, hopes, and money in a seaside villa with beautiful waves! Everyone should be happy too! I thought so… "…I thought you were really dead.

Then choose me instead. Don’t let it bother yourself, Duchess. I’ll be by your side anytime, anywhere." Even the second older brother of the female protagonist, who always looked at me like a thorn in his eyes, became a bit strange. What is wrong here?

The game's heroine had a limited time to live. Meanwhile, I played the role of the villainous friend that vies for the male leads' attention before being eliminated by the player. However, after that kid died, I made the decison on my own to exit from this story. But, what do I do? The reactions of those around me are a bit strange. "I came to the marquess’s estate because Ophelia needed a friend around her age. And now, Ophelia's dead." Their gaze seemed to be asking me why I was stating the obvious. I said it plainly. "So, I should leave now." For some reason, the two men made an expression as if they were at a loss for words. They used to consider me a fly that stuck to Ophelia's side, so why? \*Otome Game: A game targeted towards women where the protagonist (player) is female
