The Archmage Becomes the Swordmaster's Youngest Daughter

Synopsis

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. (Source: KakaoPage, translated)
