"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.

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

Mila couldn't believe how much more of a variety of genres the author wanted to try. She looked at Greyson with a scowl as she wanted to know if this system would be advantageous for her or not.

"No. Do not worry, Mila. This world didn't take that genre, it is still sticking to its original genre. I am not relevant to this world. I was just thrown here because of the author's forcing me to enter back onto his computer, which resulted in me taking his computer system as well." Greyson explained. He wiped the bead of sweat forming on his forehead as he was still not comfortable telling all of this to Mila.

"Then does this system help you or not?"

"It is helpful because it helps me adjust to this world and also allows me to see everything happening in other worlds."

"The system gives me detailed status and e-book style files regarding the other world."

"How to jump from world to world?"
