In the last episode, before Noh started to be violent apparently without any reason with a guy in the street after stopping the moving trucjk where Lee was, who ended up that guy being? Even after watching what Lee saw in the phone I didn't understand who he was supposed to be. Can someone please help me to understand that? Also why did Lee went away for a while before getting back after kissing each other after Noh aprehended the guy which he was pretending to be violent with for aparently no reason?
