What to reply to an awkward convo?

I matched with a guy I know in real life and like on a dating app. He said hey and then I joked around saying “hmm you look familiar… have we met?😂” And he replied do i know you from somewhere? 😂” (Also joking around cause we were friends). Now I don’t know what to reply but I don’t want the conversation to just end
