Unsure if it was before, but I think he 100% realized it's him when he asked Yeowoon to come over because his nephew wanted him to come (ch. 36/37). Yeowoon at some point started talking to himself out loud, a rather noticeable habit of his as Neuta as well everytime they hopped in VC, then Jigu sent him a msg as Jistar, and obviously heard Yeowoon get the notification.
Wait he knows??? What chapter did Jigu found out that Yeowoon is Neuta?? I didn’t read this for a long time, waiting for it to have more chapters
