There's No Way My Little Sister Could Be a Fudanshi Otaku

Out in the world, my sister Zhou Mo is capable of anything, the picture of perfection. But on weekends and after school, she locks herself in her room, and I have no idea what she's doing. One day, I got a text that could tell me what my sister was up to. The catch? It cost me 250 yuan. The next morning, I woke up in my sister's body and discovered that she's still a fujoshi shut-in, secretly plotting how to turn me gay and set me up with my best friend.
