Well if you'd like to try out an OC RP, I'd love to RP with you! I'm Iltu (or Rommy!), I'm a very laid back, flexible RPer. I haven't RPed in a few years, but I can show you some solo writing samples if you'd like! Honestly, your last bullet point made me go, "YES now THIS is someone I could get along with!" because I like diverse characters and headcanons as well and am 100% here for them. I usually prefer fantasy, but if there's other genres you like, I can branch out.

Also, I just looked at your profile and saw your age, so I wanted to let you know I'm 22, in case that makes you uncomfortable or you'd prefer not to RP or anything! If it's an issue, don't hesitate to let me know.
