"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

"Brother Buff? Who is that?" a petite girl asked her bulky brother.

Her brother's height is double her size, so she usually stands on the chair or climbs on his back just to talk to her giant-like brother.

"Eat and run." Her taciturn brother replied.

"Oh? Someone dared eat and run in our restaurant? Wow! He's brave!" she applauded.

The girl and Brother Buff are watching a foreigner washing a mountain of dishes. They both look at Robert with amazement and curiosity.

"He doesn't look poor, though? What if you misunderstood him? You even punched him in the face. Brother Buff! What if he sues us?" The girl exclaimed. She's climbing too much on her brother's back until she ends up sitting on Buff's shoulder.

"Hey, monkey! That dude can't even call the police." Another muscular man interjected and messed up the girl's hair. The girl grumbled about her ruined hair, but their conversation continued.

"I found a good place to stay.”
