Most of the possible AUs will probably revolve around . OwO

1. Joseon era AU (Prince YN/Guard Cheol)

2. Mobster AU (Mobster Cheol/Civilian YN, or warring mobster factions)

3. Hitman AU (Hitman Cheol/Civilian YN, or both hitman)

4. Angels AU (Cheol is a soft demon/Angel YN)

5. e AU (eCheol/Client YN)l

I'm open for any other AUs, trust me.
