"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 had been calling for the attendant or the slave that Mila had introduced to him, but he was nowhere to be found.

Kim was done taking care of Robert. He serves him food, prepares his bath, tours him around the house, and gives him a little bit of information about the world they live in.

Kim left Robert in his room to sleep, assuming he wouldn't need anything else but sleep, but Robert had other plans. He plans to wait for Mila and Christopher to come home. Also, he couldn't sleep without his thoughts being clear, and only Mila could enlighten him.

"Sir Kim?" Robert continued to go around the house calling for Kim. He went to every room as he forgot to know in which room Kimsmeth stayed.

"You’re married even in this world?"
