The Grand Line, but I'm a Marriage-Fruit User

I transmigrated into another world as a random extra and grew up relying on my younger sister.

After being away for a year, I came home to discover that my sister was pregnant with some man's child! And that man was the legendary Pirate King!

Pirate King Roger said he was going to turn himself in to the Marines. To protect her child, my sister decided to sacrifice herself.

My eyes rolled back and I fainted.

I only know the general outline of the story, but to protect my sister and her child, I gritted my teeth and decided to become the Pirate King's "widow."

After little Ace was born safe and sound, my sister settled down in Windmill Village to raise him.

With the Marines after me, I got carried away by a pretty face and proposed to a pirate.

The red-haired man turned me down. "You're Captain Roger's lover. I can't betray him."

When I found out that the red-haired man had once been one of Roger's crew, I hightailed it out of there that very night.

Before long, I married a handsome blond man.

It didn't last. My husband died at the hands of his own older brother, leaving me and a mushroom-haired boy to depend on each other.

I was heartbroken.

A gentle doctor with a pineapple-shaped head comforted me, and I fell in love again.

But the doctor had to think of his family, while all I wanted was a peaceful life. I got my heart broken again.

On my way back to the East Blue, I ran into the world's greatest swordsman, Hawkeye. He cooked, I washed the dishes; he planted vegetables, I watered them. I was happy, except that he kept asking me to fence with him using the Pirate King's swordsmanship, so I proposed to him.

Hawkeye said he needed time to think.

After I came back from fencing with the red-haired man, Hawkeye turned me down.

I was heartbroken.

Back in the East Blue, I was caught by Marine Admiral Aokiji, and my escape attempt failed.

Life is full of twists and turns, and the road is rough.

This time, I really cried my eyes out.
