I have a question about the first secret quest, for I kept walking around the graves just top left the house, but there seem nothing to interaction, did i just find the wrong place or lack something?
1. Select the save button and travel to the customer hall.
2. Look for the Gravekeeper. (has a raincoat with glasses and a beard)
He will tell you about something with the graves.
3. Go back to the lobby and proceed to Syrianna's game, the third girl in the Mainhall
(white hair with antlers)
4. Start her dialog and proceed to the 4 graves in the top right
5. Select space on S and follow the graves one by 1 until you reach the E 
6.After it you have to enter the building by collecting 3 parts to make a torch. (Note: You can collect the 3 parts and then interact with the gravestones before entering the building)
