You are facing towards the aquarium. Turn around and walk straightly behind the chairs till you find an open room in front of you. Enter the room. Slightly turn right and move towards the washbasin. Slightly turn right and move towards the refrigerator. Again slightly turn right and walk through the open door. Move towards the closed door in front of you. Turn right and there you will find a staircase. Climb the stairs. Slightly turn left and enter the open room. Now you are in the study room. Slightly turn left and walk towards the second bookshelf beside the chair. That will be the end point.
