Megami kara Ataerareta Yomei Ichinen de Yami-ochi Yotei no Fiancé wo Sukuimasu

Lady Lucille, a marquise's daughter, was murdered by her fiancé, Prince Shezard, on the day of her school graduation in her first life.

By the goddess's mercy, she is sent back a year and lives her life again, but her life ends the same way as when she died last time: on the day of her graduation.

Lucille resolves to use the time she has left to express her heartfelt love to Shezard and tell him without reservation how happy she is to be by his side.

Meanwhile, Victor, who kidnapped Lucille, reveals a shocking truth about Shezard's past. Shezard seemed to accept it, but one day he suddenly disappeared.

In reality, he had realized the limited time she had left, and had embarked on a pilgrimage to receive a divine oracle from the goddess in order to save her.

Lucille decides to pursue Shezard, but is locked in a room in the castle by Altair, who has succeeded to the throne.

Not wanting to meet her end without ever seeing Shezard again, Lucille, with the help of everyone, escapes the castle and embarks on a arduous journey.
