I was just trying to prevent the breakup of the main characters

Here's an improved synopsis, incorporating your requirements: After painstakingly engineering the engagement of the most oblivious couple imaginable, I transmigrated into a fantasy romance novel as the male lead's younger sister... only to have the engaged couple call it off on their wedding day! The culprit? Aiberg Rafaello, the female lead's infamously overprotective brother with a serious sister complex. To salvage the situation (and the original plot), I need to distract Aiberg from his sisterly obsession. The logical solution? Find him a love interest. "What is your ideal type, Your Grace?" I inquire. Aiberg responds, "I desire a woman with fiery red hair and eyes like burning embers, one who fears no one. Come to think of it… you fit that description perfectly." I only meant to save the main couple's engagement, but somehow, I've accidentally found myself flirting with the heroine's possessive older brother! Now trapped in a world of convoluted misunderstandings and romantic obstacles, can I truly fix this story gone awry, or will I become tangled in a new, unexpected love triangle?
