I'm stuck in the Short Fuse quest.
I have activated the guide, and it's seem I must put a cake, a bottle of brown beverage (some soda I suppose) and an apple in one of the student desk in the English Classroom.
I manage to get a slice of cake, a salted soda bottle, an an apple.
But I can only put the cake inthe desk, after that, I can't put any other things in the desk...
Edit: Nevermind, I finally figure I just to put one of theses items at a time, and wait for the next day...
