Gender Swap: My Own Little Sister Set Me Up During My Promotion

“Transformation + loli + younger sister + another world + dragons + sisterly love + ‘leisure’” Cen Lingling woke up one day to find she had become a girl. Having gone without a break for so long, she wanted to slack off for a while, but her younger sister tricked her into going to another world. She had only meant to spend some time having fun, but then she discovered that her soul had changed and was somehow connected to the legendary dragons... Until she figures out what happened, Cen Lingling doesn't dare return to the real world. Instead, she sets off on a brand-new adventure in the land of fantasy, another world. Basically, a series of “everyday” stories about what happens after she becomes her younger sister. I'm too lazy to think of a proper blurb for now, so just read the story.
