Long before this day, in the past, precisely in a previous life. Kavish and Kashden are your husbands whom you love so much. They are twin brothers and are the most valuable, most influential princes, and great wizards in the empire. For some complicated reason, they have to marry you. You love them so much, but they don't love you back.

Kavish is about to marry his his fiance while Kashden is expecting a baby with his second wife, leaving you all alone with your loneliness. Until they finally lost you, the intruders killed you that night indiscriminately when they were not around.. All the smiles, hopes, wishes, requests, happiness that you should have been able to give, everything disappeared in an instant following the flow of your blood dripping everywhere.

In fact it had a huge impact on both of them, they felt deep pain, tightness, great sadness, guilt, even real emptiness.. They made a mistake, which was taking away your happiness that they should have been able to feel too. Until they make a deal with God, they sacrifice everything, just so they can meet you and ask you to give them a chance and love you sincerely.. make your dream of having a happy family come true, which cannot be realized at this time because of their selfishness.

...

In short, they feel the same pain as when you are dying and slowly drifting away from life, they felt great fear and they can't stand the thought of you feeling all that when they're not around.. They are so sorry, they just want you back by their side, alive and smiling softly..

Their eyes slowly closed with all the pain of the deal, they sacrificed their lives to meet you. Meanwhile, God takes their souls into the new years, in an era where you reincarnate as someone they have always loved..
