"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

Robert could tell that the gorgeous one-eyed woman in front of him was Mila. He didn't have any doubt about it, but one thing he could not accept was how much Mila's aura changed. It was as if Mila adapted so much to the new place that she was like, "She's one of them now."

As if Mila's manners and behavior were completely like the people in this strange place for Robert.

"Did this city corrupt you?" he asked as he still refused to get in the car.

Also, using a strange vehicle is something he wanted to ask about Mila and how she managed to get one.

Finally, Mila took off the scowl off her face and laughed loudly but prettily in front of Robert, which made Robert stiffen and ask back again while stuttering.

"You're funny. You think I am corrupted? with this city?"

"As if you're not my mother."
