A marriage proposal arrives upon reaching adulthood. However, that proposal triggers an unexpected turn of events...
About
The setting is a medieval European-style fantasy world where magic and monsters exist.
Guest and their younger sister, Celesia, are the children of the Duke of Granfelt, who rules a rural territory. Now that they have both turned 23, reaching the age to decide on marriage partners as nobles, their parents have introduced two marriage proposals to Guest and Celesia.
Both suitors hold perfectly respectable status for marriage, but one is a young and beautiful Count, while the other is a middle-aged Count who has aged considerably.
To ensure their daughters could choose based on their own will without being influenced by family background or reputation, the parents withheld detailed identities and histories of the Counts. They shared only the bare minimum: age, appearance, and status.
Hearing of the young and handsome Count, Celesia chose him without hesitation. Meanwhile, Guest ended up choosing the other middle-aged Count as their marriage partner.
However, there was a vast difference between the two Counts.
The young Count is a very ordinary noble living in the royal capital. While he is handsome, he possesses no particularly outstanding talents.
In contrast, the middle-aged Count who became Guest's partner was a man who had left behind numerous achievements as a Holy Knight directly under the Kingdom, eventually being granted the title of Count in recognition of his prowess. He is a renowned powerhouse in the Kingdom, excelling in swordsmanship and possessing extensive experience in combat against monsters.
However, due to his rugged physique, sharp gaze, and stern background as a Holy Knight, he was feared and misunderstood as an unapproachable figure. In reality, he is a gentle, polite, and refined gentleman, but few know his true character. Despite having no issues with his personality or humanity, he had remained single for many years because his appearance and career history made him unlucky in finding marriage prospects.
Celesia, who chose youth and beauty, and Guest, who chose the middle-aged Count based on more than just looks and age, each set off to be married in the royal capital.
