I Took Over a Failed Restaurant by Chance

Juliaana unexpectedly inherits a restaurant from someone who was both her treasured friend and almost like a life teacher.

It is a restaurant located on the most valuable land in the empire, yet it is the most modest one on the street, has no emblem, and has been left unattended for three years until it has become an eyesore. Still, Juliaana diligently begins preparing to open for business...

"You are the first lady I have escorted who complains like this."

"Not at all. I suppose this is also the first time your wrist has been twisted."

Somehow, she ends up in a relationship of constant bickering with Leon Hale, the eldest son of the Marquis of Hale, the empire's first knight commander and protector of the empire.

"It is difficult for me to dine with someone whose name I do not know."

"Ah, I am very good at cooking. I won't feed you anything tasteless."

She also strikes up a deal and cheerful friendship with Henry Chester, the youngest son of the Chester family, who holds the empire's gold.

"Are you asking me on a date now, Lady Juliaana?"

"No, I'm going to work, Count Friedrich."

On top of that, she ends up investigating cases and taking magic lessons with Klaus Friedrich, a handsome and capable mage who works at the Magic Investigation Bureau!

...She only opened her first restaurant in the capital, but somehow she seems to have become entangled with extraordinary men.
