Why Does My Baby Have To Be A Villain?

When I woke up after banging my head on the road, I possessed a novel I enjoyed reading. Although not a single line about her appeared in the original, she is the only daughter of a wealthy family with enormous wealth.
I was embarrassed for a brief moment but later thought that this was a great opportunity. This is my favorite novel, and I can finally meet Locus, the villain of this novel.
At the same time, this is my only chance to save Locus!
I clenched my fists as I made up my mind. As long as I’m here, Locus’ life will end happily without any shortage. Especially without being pushed aside by the main characters! I will paint his path with gold!
To do that…
‘Locus had an unhappy family history since childhood.’
I have to erase this one line from the novel.
Really, this is ridiculous, why does my baby have to be a villain in the first place?
