i feel why there are many of the same bts, nct, and exo rps is because people only give attention to them. people feel more comfortable talking to something familiar. it's okay to talk to someone and not know their model/fc. dont just avoid them because you don't know who they have as their pfp, they're just like any other rp. it's also okay to step out of your comfort zone and have an idol you dont know much about as your fc. it's not like you have to write a 5 page essay about them just to use their pictures.
