You are facing towards the wall. Turn right and walk through the open door. Slightly turn left and walk through the half open door. There is an open room to your left side. Move a bit forward in the corridor. Now turn around to your right and walk through the open door. Now you are in a room which has white desks and black movable chairs in it. Walk towards the first black chair and stand behind it. Now you are standing in between the curtain and the black chair. That will be the end point.
