A violent and muscular boy who dreams in becoming a national champion, unexpectedly turns into a cute girl, how will “she” achieve “her”dreams?

The main character is Pan Gamma Vi Gen. He is the captain of the legendary black vessel. Pan Gamma Vi Gen is lazy and clumsy -- that is him when is resting. But once Pan decides to work, he is the best man available. Pan says things that normal people can hardly understand. And he doesn't say much, he only gives lots of clues.
Everything starts when Captain Pan let Mia and Tuban Sanoo be aboard. Mia is a princess of a fallen country and Tuban is the best, people say, swordsman as well as strategist. Although Pan Gamma Vi Gen is the main character, it seems Pan, Mia and Tuban are the main characters as Mia and Tuban appear in all episodes. Mia is looking for science to restore her county, Ontana. Tuban is protecting Mia as the will of someone Tuban trusted. Pan Gamma Vi Gen agreed to take Mia to where she could locate the science in exchange of her virginity. (Don't get Pan wrong here, I believe he meant something else but at this moment, Mia's virginity is all I can guess.)

I came here with only the goal of revenge.

I overthrew the Tulkan Empire, a single nation that dominated the continent.

I had always succeeded in gaining victory. I had accomplished all I needed to and was satisfied.

That’s why I accepted my approaching death. I no longer had a reason to live.

And so my heart stopped beating.

I definitely felt it stop.

However, what in the world happened?

“It’s not black magic and it doesn’t seem like an illusion either.”

A boy with short, black hair was reflected in the mirror.

I looked exactly like when I was 14, which was 20 years ago. A young boy, who hasn’t lost his baby fat yet, patted his cheeks and murmured, “How is this possible?”.

I had returned.

To the time filled with my regrets.

Her best friend and her husband cheated on her. If that were not enough, he killed her, his terminally ill wife. Ji Won, who died like that, miraculously returned to ten years earlier. In order to change her future, Ji Won pledged to hand over her ill fate to her "best friend" Soomin.

'So, marry my husband instead of me.'
