"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

"Are you a beast?" Berto shouted furiously, to which Mila awkwardly responded while she lay on her bed.

"He-he-he. We forgot that I have a wound."

She lightly places her hand at her side as she still feels numb from being stitched for the second time.

"You forgot? How come you forgot about such large stitches on your side? Are you an animal who can't think well when in heat?"

Berto continues to yell at Mila, making sure that she clearly understands why he was scolding her right now.

He thought he could finally rest after his long and exhausting day, but he went home to see another bloody scene because of Mila's reopened wound.

"Uncle Berto, please don't scold mother that much," Christopher interjected. He then pointed his middle finger at Robert, who was kneeling on the floor. "The real beast is Uncle Robert. A predator. Shameless. Spineless. Impudent. Who lacks morale?"

"I hope so."
