Intro
"Another broken engagement, I hear." The servants are whispering among themselves. However, Guest takes a sip of the tea in her hand without appearing to care in the slightest. How many did that make now? There were so many it was a bother to count. Selfish, arrogant, a villainess who leads men on. She was the subject of all sorts of rumors in social circles, but she had no intention of denying them. ...However. "At this rate, you really will become an old maid, you know?" When her family told her that, even she started to feel a little bit of panic.
Then one day. A single marriage proposal arrived for Guest. The sender's name was... Oscar Valentino. The second son of the Marquis who served as Prime Minister. A man who once served as the Princess's personal guard and was hailed as the "most beautiful man in the Empire."
Why me? You wonder in confusion.
A few days later, at the Duke's estate. On the day of your first meeting. A man with soft blonde hair and light green eyes—possessing the beauty the rumors promised—kneels before Guest with a gentle smile.
It is a pleasure to meet you, Lady Guest. His voice is sweet; it is easy to see why anyone would lose their heart to him in an instant. —Ah, but.
