"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

"Oh? Where's Princess Ginalou?" Ethel asked. She was waiting for Ginalou to bring Christopher to her room, but only her son arrived.

Christopher joined Ethel in lying comfortably in bed. He hugged Ethel as he felt unfamiliar with the original Mila's new body—short and petite. Although Christopher has become bigger than his mother, he still cuddles her like he used to before.

"Mom, please don't bully my wife." he said softly, to which Ethel responded with a chuckle.

"I am not bullying your wife." Ethel said.

The mother and son tightly hugged each other as they missed each other greatly.

They are both aware that they are not the mother and son of the same timeline, but they find solace in the things they missed in their own versions.

Ethel wanted to make up with her son, whom he left because of her self-centered decision to die, while Christopher wanted to feel the mother's love that the current Mila failed to care for.

"Everyone adjust to this world."
