From the outside, Nana’s life seemed simple. She had everything she had ever wanted: a cute but rascally pair of twin brothers, a best friend, and her own restaurant. Nana couldn’t ask for anything more; she was happy and content in her life.

A world filled with heroes with superpowers. A world attacked by calamity fiends. A modern world filled with wonders and dangers.

An engagement paper to lock one’s destiny. With her family facing financial difficulties, she marries into the family of the richest man in Qingzhou as his wife. Her Mother-In-Law’s doubtfulness; her husband’s childhood sweetheart; her mean elder sister-in-law; her narrow-minded younger sister-in-law… Being inferior, Sang Wan withdraws without a choice. As time passed, she ended up being lonely and died tragically.
