Fav Shumika AU is most definitely any kind of royalty/fantasy AU!! I’m a huge hopeless romantic so I love those “forbidden love” and “love conquers all” type stories that can be done with Shu as the prince and Mika as the commoner.. Other than that I also love mafia aus.. Wabimika my beloved I’m insanely obsessed with them and have so much lore for them already in my mind LMAO
