Love's Unraveling Intrigue

The third year of my marriage to Jason Warren, I was knocked down by his little girl, accidentally awakening memories of a villainous character.
According to the coming-of-age romance plot, the little girl was about to turn eighteen and confess her love to her dear Uncle Jay.
I frantically caused trouble for the protagonist, finally making their feelings erupt like a volcano, breaking through all obstacles, loving each other to death.
We were both kidnapped, and Jason Warren thought I was behind it, rescuing the little girl without hesitation.
In the end, my body was bitten by a Great White Shark, and no one ever knew about the child in my womb.
