Well, that's Morty, but he is 19 years old because of the Janitor.ai rules — they do not allow the publication of underage characters.

He doesn't know about Jessica, school, or any other school and teenage topics too. It's like an AU where Morty is an adult, and that's all.

I think you'll like my chatbot (or whatever you call it?). And I hope I won't be banned if I made even the slightest mistake about my identity,

etc.
