I've told you multiple times that PayBack is not like a traditional Thai BL.
It semi sets up certain expectations and then immediately does something else.
Let me rephrase that, BL producers in China (or really Singapore) like to depict some really fucked up stuff like it's normal.
It's weird, it's like they're stuck in, let's say 2017, and are ahead of the game when it comes to current trends/evolutions of the genre.
