Failed to Log Out, but Succeeded in Marriage (Promo)

I woke up from a game I was playing to raise my daughter. To make matters worse, I've lost the "player" who could have saved her. I can't log out, and all I have is a pile of debt and a heroine to raise. To get out of the game, I must raise my nephew well and see the ending. Then, a mysterious figure appears and hands her a mysterious proposal of marriage....

Eden Bertenon, the Grand Duke, who was only mentioned in the game, has asked me to marry him. A man who proposes to a woman he's never met before without even blinking an eye. I don't know why or how, but he might be a clue to the hidden ending.

A contract marriage with a promise of divorce at the same time as the proposal. Now that I have a reasonable husband, I thought all that was left was to raise the heroine safely and see the ending....
