From a Soulless Daughter to a Stirring Conqueror FASDTASC

A young woman about to enter the University of her dreams suddenly dies an unlucky death in a car accident. She wakes up in an identical body. But this body? A 14-year-old child?
A soulless princess? Hmpfh, I'll become the most stirring person!
A weak constitution? I'll show you the meaning of weak.
Dull eyes? Her cold dominating eyes can force you into submission.
Her newfound mother and father. No one dares to disgrace her in front of her powerful parents and noble little siblings. But nasty rumours spread through cracks. She'll squash those nasty bugs.
God gave me compensation for my losses.
If I couldn't become the President, then I'll just become the Ruler of this world!

A shadow follows her around. "Wifey! Wifey! You conquered my lips now you have to take responsibility for me!"
"You, you shameless old man!"
"Old man? But I'm only 19. If you want I can go back to being a cute dumpling." Poof!
"Hehe, I'll punish you now!"
"Waaaaaaa! Wifey! How could you wrong me? Wifey is a mean cougar!"
.................cougar? me? This little black belly two-faced bastard!
