After Edith lost her parents in an unfortunate accident, she was taken in by her paternal family, the House of Earl Oakridge, where she was subjected to cold treatment by her uncle and aunt, who became her foster parents, and her cousin Dalia, who became her foster sister.

One day, a marriage proposal arrived at the House of Earl Oakridge—a proposal for the Earl's family to marry Lionel, the eldest son of the Marquis Granvelle family, to whom the Earl's family owed a large sum. This engagement, however, had a catch. At the initial meeting, Dalia was horrified by the sight of Lionel, who was afflicted with illness, and pleaded with her parents. As a result, Edith was made to become engaged to Lionel in her place.

"I'm sorry to be engaged to someone like me. The doctors have given me only a year to live, so I don't think I'll make it to the wedding. I apologize, but could you bear with me for just one year? You can think of it as a one-year engagement contract."

Edith began to devotedly support Lionel, who seemed so sincere when he said this. In a world where the power of magic was said to have been mostly lost long ago, Edith actually possessed a special ability inherited from her parents.

After Edith began to support Lionel by his side, he showed a miraculous recovery, gradually regaining his former handsome appearance. Such a man came to utterly dote on Edith...

This is a happy-ending love story.

Also, I apologize, but I have temporarily paused accepting comments.
