Suffering under conditions (DC)

Origins

There was a man of great age in the distance. He sat near a table thinking about something deeply.
The man was short in stature but wise in character. He was slim with gray hair from old age. The man's skin, rough in texture, was perceived as a testament to his struggles.

The solutions he was looking for were alternatives to what he had planned. However, he found none.

What was his plan?
It was a project he dedicated his life to find happiness for his daughter. It always infatuated him, the thought of being happy and dreamed of it because he hadn't felt happy in a while.

His daughter, who was named Luotali, was a young girl who was tall, healthy, and beautiful.
She died young due to an unknown disease that struck her. In her short life, from what the man could see, Luotali never had a happy experience. It made him more motivated to complete his plan.

Since there was no other way besides the current plan he decided to stick with it.
Although he knew that the solution would cost his dear Luotali a lot of harm to reach his goal. This solution included his daughter's corpse because she was the perfect vessel to be able to reach the goal.

Just how would Luotali come across these hardships?

It was through a simulation that the man created during his research.
It included different chances to escape. But first, she would need difficulties to overcome.

The man thought that if the simulation was successful Luotali would become alive in the simulation.
The simulation would imitate the real world giving her a sense of comfort to be able to succeed.

The man thought if she managed to achieve the goal while he was alive (or not) his daughter would be happy regardless.
Perhaps Luotali would escape to a reality where they were all happy.

But would it be so simple?

At last, when the man had finished the experience, he succumbed to an illness he held for a while. In his last moments, he thought about his daughter and how happy she would be.

The corpse woke up. Not physically but subconsciously.
She moved so slightly at first to allow the skin of the corpse to crumble away revealing her flawless skin.
Immediately after, she began to open her eyes, revealing her dark brown eyes.

Originally the house where the man lived was bare but clean. The walls were black contrasting the white furniture. The house wasn't old but modern.

The room the girl rested in even before the man's death was her bedroom. The man had never experimented on her but let her corpse rest on the bed. It was to have her be comfortable to enable the experiment.

But would his dedication to his daughter reciprocate back to him?
