"Why do the main character's parents often get the short end of the stick?"
That is what Mila asked while looking up at the sky. She was grumbling toward whoever sent her inside the novel she read before she died.
She becomes the mother of the main character, whose parents are both dead. Mila's character was merely a tool for the MC's character development.
It's a simple, fix-all solution. The author wanted to make the audience instantly sympathetic towards the main character, and the best thing he did was to have the MC's parents die.

After she avoided her death in the original plot, death flags kept coming for her. 

Will the original plot not end if she's not dead?

Main character's parents must die

"Do I look strange? Can you find a lighter shade for my eye patch? I look really hideous!" Mila stares at her own reflection in the floor mirror (floor length mirror).

She turned and repeatedly checked her uniform as she felt like she was going to attend a Halloween party rather than work on the household. The uniform consists of a baggy black dress, a white apron, and a hairband. She looked intimidating as she was literally filled with dark colors. Her hair, her clothes, and her skin are all so dark that you can still tell she's a warrior rather than a helper.

"How the hell are these clothes comfortable for a maid? How can they do household chores with these uncomfortable clothes?"

"Why don’t you use Ethel’s name as well?"
