I'd love to help you out lovely! Sorry for the late reply, I've been busy. If you message me privately on my main account @logicalmuke I'll give you some writing tips and some feedback. Coming up with preference ideas can be very difficult. Usually I have to go to other preference books to help me get some ideas. Going to other preference books is totally fine to get topic ideas, just make sure you don't completely copy what happens!
hope you have a great day! and I'll be anticipating a private message on my main profile ❤️
