Akumu kara Mezameta Gouman Reijou wa Yarinaoshi wo Mousakuchuu

Farrara, the daughter of a duke, has her engagement to the crown prince broken off, leaving her mentally ill and confined. One day, she dreams of her fiancé being taken away by a former friend as Choko, the daughter of a company president.

"Who is Choko?" "Has my engagement been broken off?"

Waking up from a nightmare, Farrara finds herself back at age 12, the day after she was engaged to the crown prince! She doesn't really understand, but she doesn't want to live a life that's the same as her dream. Reflecting on her arrogant past, she resolves to start over, aiming for a brighter, more enjoyable future. This is a happy fantasy about starting over, featuring the struggles of Farrara (from another world) and Choko (from the present).
