"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.

Will the original plot not end if she's not dead?

Main character's parents must die

Mila's response brought chaos to Robert on the inside. His mind rejoiced, and his heart beat like a drum.

Mila's mischievousness returned as she teasingly smiled and drew Robert's collar closer to her.

Although Robert is itching to jump on Mila, he still restrains himself from getting excited.

'It's better we didn't do it if after this she runs away again.'

Mila kissed Robert as her hand gently caressed his muscles.

Robert couldn't restrain himself anymore as he pushed Mila on the bed. His mouth moved erratically, as if he were devouring Mila, and his hand traced the outline of the body he desired.

Robert's ears burned into red as soon as he heard Mila's moan while his hand touched every part of Mila.

He then had a smile after touching Mila in between her legs as he commented,

"It's a menstrual hygiene device, my lord."
