I Was Just Trying To Stop the Main Characters From Breaking Up

I’ve been reincarnated as the male lead’s younger sister in a romance fantasy novel full of misunderstandings and pointless struggles. Thrown into the story, I took it upon myself to connect the frustrating main couple. However, on the day of their engagement ceremony, they suddenly declared their engagement broken!

And at the center of it all was the female lead’s older brother, ‘Iverc Raffaelo.’ Iverc, the monster duke, was a notorious fool for his sister. To lessen his obsessive attachment, I figured a romantic interest would be the best solution.

“Your Grace, what is your ideal type?”

“A woman with fiery red hair and eyes that resemble a blazing flame, one who is never intimidated regardless of who stands before her. Ah, now that I say it… you resemble my ideal type.”

I was only trying to prevent the main couple from breaking up, but did I somehow end up seducing the female lead’s brother in the process?
