Anata-tachi ni Suterareta Watashi wa, Youyaku Shiawase ni Nare Sou desu

Ariane was raised with the protection of spirits and shared a childhood with Lionel, the son of a duke, with whom she promised to marry. They enjoyed a content and joyful life together until Ariane's father, a count, arranged for her to marry the second prince against her will and kept her imprisoned in their home. Hoping to be reunited with Lionel, Ariane suffered through her isolation, but eventually lost the spirits' protection and was neglected by her family, leading to severe physical and emotional distress. At the same time, Lionel began working in secret to reclaim Ariane.
