"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

"I'm sorry," Robert mumbled as he stared at Mila's face.

With her eyes closed, and with her light breathing, Mila looked like a dead person. Her skin doesn't have the same dark color as before, as she looks more ill with her lips, which look dry and bruised. The sudden loss of her weight shows how much blood she lost from the gunshot wound.

Robert cleaned and changed Mila's clothes for her to have a comfortable rest to recover. He only sat at the edge of the bed as he hesitated if he deserved to be by Mila's side.

"I should have talked to you instead of running away." He continued to softly speak, for him not to wake her up. He gently caressed Mila's left closed eyelid as he remembered how Mila lost her left eye. "I should have known better after your eyes got plucked out. You were too vulnerable at that time. I should have known better."

"Why? What will you do if you know?" Mila suddenly asked while still having her eyes closed.

"I’ll be by your side.”
