Kurokawa Risa is an ordinary office worker, who has practiced lots of cooking while living alone. One day, she wakes up in another world, with a concerned little spirit hovering over her! She has apparently been transported to a magical, spirit-filled realm by the will of the goddess, and there is no known way for her to go back. She is taken in by a wealthy couple, and they and her new spirit helper treat her with nothing but kindness. There is one problem, however–the food in this magical world is gross! Risa insists on helping the household cooking staff prepare a traditional meal from her world, and it is a big hit with her hosts. Soon Risa knows what she should do in this new world; she should open a cafe and treat everyone to delicious food!

“Can a person suffering from amnesia have a total change in personality?”

The question lingers in Feng Ning’s mind.

Other people treat her coldly, claiming she is insidious, cunning and selfish. There were even rumors of her not being a virtuous wife and having illicit affairs with other men. However, she had no such memories.

After waking up from a heavy fall and knocked her head, she is now polite, treats people in good faith, and tries her best to get on her husband’s good side. No matter what she did, the past could not be undone and despite having no memories of it, Feng Ning calmly accepts her fate and slowly tries to mend things back. But why must fate be cruel to her? What did she do in the past to deserve this? In the first place, how did she end up in this sorry state?”

Cheng Yujin was the elder twin sister, who was supposed to be engaged to an excellent man. However she later learned that her fiance, Marquis Jingyong, had proposed to her because he mistakenly recognized her as her younger twin sister.

While Cheng Yujin was the villain who replaced her sister’s good marriage, kept framing her sister, and hindered the main couple to be together. A really wicked older sister and poisonous ex-wife.

After the younger twin sister was reborn, she revealed Cheng Yujin’s ‘conspiracy’ early on. Everyone scorned her, and her so-called fiance was indifferent. Cheng Yujin sneered and tore off their engagement letter in front of her fiance.

Everyone was gloating and happily waiting to see her regret her actions. However, before Marquis Jingyong had a chance to see Cheng Yujin’s regret, he saw his former fiancee marrying her uncle.

The ninth uncle of Cheng family was truly a hidden dragon, his real power frightening everyone.

“Married rich for three years with no child born. Just when she was finally cured of infertility and ready to give him a child, he brought home his pregnant mistress in high profile.
