Also known as: After Switching Souls with My Older Sister, She Keeps Trying to Conquer Me
To keep me from starving in the future, Dad worked hard and finally became a notorious profiteer in Baihua City.
To make sure a lousy student like me wouldn't fall behind from the start, Dad spent a fortune to buy the best high school in Baihua City.
To make sure I wouldn't end up single for the rest of my life, Dad shamelessly married the most beautiful single mother in Baihua City, because she had a pretty daughter.
"Dad, be honest with yourself. Are you sure you didn't make your dirty money just to splurge on yourself? Did you really buy the school for anything other than the beautiful principal? And did you really marry that beautiful single mother and principal for anything other than your own pleasure???"
"All right, I'll forgive you, since my older sister is so pretty."
Wait a minute...
Why did my sister and I switch souls when I woke up?
"My dear little brother, to make sure you don't do anything bad with my body, starting today I'll be keeping an eye on you twenty-four hours a day, around the clock. Yes, even at night."
"No! I don't want to be a girl. I want to switch back..."
