The Gender-Swap Diary

Fifteen years ago, the baby girl my father brought home from a dumpster completely changed Liu Feng's life.

"My little sister is a genius, devious to the core."

"My big brother is an idiot who does nothing but pick fights all day."

Then, one day, we swapped bodies. I became my own little sister, and she became me.

What do I do if my sister uses my body to build herself a harem? Help, I need answers ASAP.
