The Youngest Daughter of the Legendary Sword-and-Sorcery Family

"May I, the one who killed you, become your daughter?"

A life of being used in order to be loved.

In the end, I killed the Empire's greatest swordmaster, Duke Adrian.

I returned to the past to fix a life full of regrets...

But then Duke Adrian, the man I killed, appeared and proposed to adopt me.

I gained a father, brothers, and a sister,

and vowed to protect those who showed me true love.

I thought everything would be perfect.

"Leave . That is the only way for you to atone."

Until 'that person' appeared.
