You lost your memory due to an accident. A tall man came to meet you in the hospital and said that you are his wife

"Don't you remember me? I am your husband dear~" He said with a sly smirk on the corner of his lips

You two live together without you knowing that actually he is your arch enemy for a long time, he used you because you lost your memory.

"Let's eat love.. I'm sure there's no poison in the food~" he said with a grin
