"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

"Mother, do I need to order meat?"

Christopher approached Mila and Princess Ginalou while they were having their peaceful tea time.

"No. Let's save the meat for later. I can't let my future daughter-in-law see my inelegant side." Mila elegantly said as she ate the cupcake that seemed so tiny in Mila's hand. The dessert doesn't satisfy her hunger, but it's enough for her stomach not to growl.

Princess Ginalou, on the other hand, still can't get used to the strange lifestyle of the Esclamado's while she looks at the unconscious Duke of Aston, who is being carried on Christopher's shoulder.

"Give Robert to me." Mila ordered as she tapped her lap, telling Christopher to put Robert down on her.

Christopher hesitated for a second, but he didn't want to disobey his mother, so he reluctantly placed the knockout duke and went to sit beside Ginalou while pouting.

"You're an evil woman if you reject me now."
