Thanks friend, I'll download it now and try to play again, I just forgot, I'll take your word for it.
Enjoy.
Once that becomes part of the story, be aware that you can only pick the blue flower on Tuesdays. It will show in the scheduler on that day, just don't be confused if it's not there on other days (that can happen if one - like me - doesn't read the story properly and misses the Tuesday part).
Click the lost books when you see them, there are four available on each day, one either in the living room or in the bathroom of the campus, the other three in the university, the locations are random. Apart from getting a little extra money or house points, you need to collect a certain number (not many, but it's something to keep in mind) to unlock one story arc with the librarian.
House points are only important in S1, only the winner house gets to make a trip to the city on weekends. In later seasons all houses get there, but the winner gets a few bucks as reward. Once the duels start, they are the easiest way to win the competition.
This Harry Potter hommage can be little bit annoying until you get the hang of it.
