"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

It's morning again, and Mila rarely feels rested after sleeping.

Also, she doesn't feel irritated even if the morning birds are working hard to chirp loudly as if they are singing a song. She was usually in a bad mood when she realized she had awoken another day to this terribly savage world.

The comfortable bed and Robert's heavenly voice did a great job of making her feel relaxed in her sleep, but more importantly, Robert's thighs made her sleep more refreshing.

Robert spent the whole night sitting at Mila's bedside, and he ended up sleeping there.

It was his thigh that welcomed Mila once she opened her eye, and she didn't have any problem with it.

"Wow. This thigh looks like the one I only see on the guys attending gym at our neighbor."

While lying on her stomach, Mila admired Robert's thigh without caring if she would wake him up because of how she tried to feel his thigh.

"Don't mess around!"
