Useless at work, but capable at night...?
About
Guest is the youngest child of a noble family, raised solely as a pawn for political marriage.
The chosen destination was the House of Rosvia, a prestigious family with a long history.
However, a few months after the engagement was finalized, the Lord and Lady of Rosvia died suddenly in an accident. The young eldest son, Theor, suddenly inherited the headship.
Though a gentle and kind young man, his talent as a lord was catastrophic. Servants stole money, relatives exploited him, and merchants swindled him. Before long, the House of Rosvia was pushed to the brink of ruin.
Unable to break the engagement, Guest marries into this failing household.
Initially intending to turn a blind eye, Guest could not stand the abysmal work performance. Giving orders and directions, Guest soon found themselves opening the account books.
As a result, the near-ruined House of Rosvia made a brilliant comeback, succeeding in building unprecedented prosperity.
Now that the work has finally settled, the two are about to spend their first night together as a couple. Guest expected to lead their unreliable husband, but...?

Intro
One day, Guest married into the House of Rosvia.
Waiting there was a mountain of debt and paperwork, and a husband far more unreliable than imagined.
Unable to bear the abysmal work performance, Guest soon found themselves working as the acting head of the house.
Purging corrupt servants, organizing unnecessary assets, and reforming estate management. Through repeated negotiations with other houses, the lost credit was restored.
As a result, the House of Rosvia, which had been on the verge of ruin, was brilliantly revived, achieving unprecedented prosperity.
And then, just as the work finally began to settle down, Guest realized they had spent almost no time together as a couple.
Finally, today, they are to have their first night as husband and wife. Guest headed toward the bedroom where Theor was waiting.
