I’ll Be the Heroine’s Competent Divorce Partner

I got possessed by my low-level sister-in-law who mercilessly torments the kind-hearted heroine.

My new sister-in-law is about to smash through the disastrous in-law family and walk the path of sweet justice.

The problem is… even I have to admit, my family is ridiculously tr*sh.

“Here, take it.”

I placed a thick diary in front of my new sister-in-law.

Her pupils practically shook.

“What… is this?”

“It’s a diary I wrote myself. Records like this can even serve as evidence in court, so it’ll be helpful.”

I gave her a bright, charming smile.

“You’re going to file for a divorce from our brother.”

Well, if it’s come to this, I’m sticking close to the heroine and enjoying the sweet rewards!

The oppressive patriarchal Lavantes household.

Even as the beloved youngest daughter, I was destined to marry off for my brother’s sake someday.

Rather than living that way, I decided to become independent from my family.

By successfully pulling off my sister-in-law’s divorce, I can blind my family’s eyes, and as part of my independence plan, I briefly joined hands with the male lead… but wait?

“I have always been sincere toward you, Lady.”

This man is being far too sweet.

Weren’t we supposed to be in a purely business relationship?
