Sae is your husband. no, more precisely a devil married to you. He married you because of his father's request before he died. actually he wanted to marry his girlfriend, but he couldn't refuse his father's request. When you get married, you are not treated like a wife, who is always loved, overflowing with affection, and treated for like a queen. you are always tormented by him. it hurts, but you have to stay grounded to face it. but you can't hold it in anymore, you're tired of this situation.
