Manga/manhwa where the female protagonist reincarnates into a game world, buys a house, and makes medicine for people

Question

I am trying to find a manga/manhwa where I remember only parts of the plot. Sadly, I can't say whether it is a manga or an manhwa. Here's the plot:

The female Protagonist reincarnated into a game world where she attends an academy. After the story of the game ends, she realizes that the game had an add-on. In that arc, I know that she bought a house and makes medicine for the townspeople around the area. But the house belongs to a sickly man whom she heals with medicine.

The house belongs to the man before she heals him and he is the head of a trading company but retired because of his sickness. The Daughter/granddaughter takes over the company and is the Female lead in the addon i think.

I can also remember that the manga/Manhwa was finished and had rougly 50 chapters? In the first half she knew the Story and in the second half she only read about it. The Second half takes place in another Kingdom. The age of the Protagonist is around 16-25

Answer 1

This is The Villainess with Special Circumstances, aka Rebirth of the Villainess: The Life of Letizia after the Engagement Annulment, also identified here.

Leticia, a daughter of a duke, has her reasons for trying to get her engagement to a prince ended. She successfully achieves her goal, and the prince declares their engagement over. She believes all is good, until one day, the memories of her past life as a nurse suddenly come back! Because in her past life she had such a grueling job, in her new life, she wants to take it easy enjoying her favorite alcoholic beverages. She starts living in the countryside, hoping for an easy life, but she gets mixed up in one problem after another. A fantasy about a young lady who just wants a simple life, but is forced to run around trying to get the laid-back life she dreams about!

It's a Japanese manga and ran for 4 volumes and 26 chapters. The first two volumes are the "main story", the latter 2 are the sequel. The sequel involves a different heroine and the scene from the question is from this half.

Leticia buys a mansion with the intent of using it as a clinic and healing the people living in the nearby villages - the mansion is roughly in between them all, so it's both the only place close enough to all the nearby areas and the only place large enough to act as a clinic.

She quickly runs into the heroine of the sequel, who wants to buy the mansion, and tries to take it with her wealth - it's not revealed immediately, but she's a daughter of a prestigious merchant. She runs into a child asking for help with "grandpa", an old man who lives in a secluded small house.

She's able to alleviate his symptoms, but not fully heal him. A few days later he rewards her with a giant stack of money.
