The best roleplay intros are the ones that don't tell me who I am
The chats I keep coming back to are usually the ones where the intro gives me a situation, not a whole identity. If it starts with “you’re my childhood rival who just moved back to town,” I’m already locked into someone else’s story. Give me a tense situation and let me figure out who my character is, and I can take it in a bunch of different directions. I’ve done stuff like cautious ally, undercover detective, total stranger, all with the same character on Emochi. That kind of freedom makes a huge difference for longer stories.
