Reborn as the Villainess, I Win the Coldhearted Brother’s Heart

On my first day after I transmigrated into a book as the villainess, I decided to change my fate.

I wouldn't be cruel, steal anyone's love, or cause trouble.

I only wanted to be a good person, treat others sincerely, and live a quiet life.

But who could have guessed

My aloof older brother started looking at me more and more tenderly,

While the obsessive second male lead held me in his arms and clung to me like a madman.

The original heroine grabbed my hand. “Give the second male lead to him!”

Me: ? This is an option?

A bad ending turns into a happy one, so why is everyone suddenly getting paired off?
