After Transmigrating into a Book, Don't Expect Me to Be a Widowed Child-Raiser Again

Guys, who can relate? I only read the romance novel my older sister loves most, and somehow ended up transmigrating into its world.

Huh?? Why did I turn into a woman?! Holy crap, these boobs are huge!

Wait, let me think about the original character's fate first...

What do you mean I'm the daughter of the Duke of Smollett, and I'll be forced to become a widow and raise a child on my own?!! Just because the male lead dies in the end?!

No way. For the sake of my future happiness, this time I'm changing my fate and stopping him from dying on the battlefield!

Deloque, don't even think about making me a widow with a kid to raise again!
