I Must Be Doing It Wrong

Zhang Cheng wakes up one night having transmigrated, and the story seems headed toward a good-for-nothing young lady's rise to power, ruling the world and gathering a huge harem. But why are all the people flocking to her girls?! Every handsome man either treats her as his lifelong best friend or his sworn enemy. Zhang Cheng can only say, what the hell. Zhang Cheng still doesn't know she's transmigrated into a harem-seeking novel. Through a twist of fate, the male lead of the novel has become a female lead... Readers, please note: 1. No ranking spoilers, please!!! 2. ...It's a little weird, so don't read if that's not your thing. 3. Updates are slow. I haven't decided whether it'll be a one-on-one romance or a harem either, so I'll figure that out later.
