So I ended up MTLing a. Chinese BL novel a while ago, modern, set in high school where the MC is great at scheming for making $$$ and unofficially is in charge of all the school gangs. I believe his mom gets remarried and his new step brother (ML) is now at his school and shenanigans ensue. I remember there were a lot of madcap hilarious moments where MC is trying to make money and lots of moments where characters (including the ML) went "who am I ? where am I? What's going on?" from MC taking advantage of unexpected twists. Anyone familiar with this?
