Hi everyone. I am new to this type of the RPG game.  I have stuck after the library quest.

To be clear, I have:

- Gain access to the Bouken City

- Gain access to the restricted part of the library by completing the quest in the tower west of the city

- Defeated Demon (even it seems I haven't get this quest)

- Defeated the demon girl in the Old Mine and rescued Momani.

I now get stucked: There's seems to be no information in the restricted section of the library. The old man in the Adventurer's room send us to the library. Then he mentioed that there's a certain fairytale about blessing. The protagonist mentioned that we need to find the origin of the tale; and proposed to have a drink. Now I cannot proceed anymore: there seems to be no book in the library about the tale (well. there's a book bout demon and demontress, I cannot decipher it); I cannot find the old man anymore; I did not get any information in the after-drunk dialogue, and now everytime I drink I will be directly send back to the inn.

So what should I  do next?

Thanks for help.
