Looks like I didn't Google it hard enough. Excellent answer.

<p>I'm talking about the notebook seen in the episode 21 of Amagami SS. She said it contained something that could make her leave the school (maybe being expelled?). </p>

<p>If it's that serious, could it be a crime? Did I miss an important plot detail that explains it? Do the contents even get explained in another adaptation of Amagami like the manga or the VN, or are they completely unknown?</p>

This was bothering me from the end of S1 all through S2, but I forgot about it by the time anime SE opened. Unfortunately, it doesn't seem like I'll get a very fulfilling answer...

Logan's answer was fulfilling enough for me.

I didn't mean to say that it wasn't a good answer (it's probably the best we could get). Rather, I'm disappointed that it's not touched upon more in the original VN.

Oh, I guess you're right. But again, the theory they worked out on Logan's link seems to be reasonable enough to take it as an (almost) definitive answer for the mystery.

There is no mention of the exact contents of the notebook in the original VN or the anime. There are a couple of short sequel games which I have not gone through, so in principle there could be some explanation there, but given how important this is I doubt they'd want to relegate it to a side-game. Hence, the authors have definitely and deliberately hidden what is in her notebook.

However, there are some good theories. The most common viewpoint is that she was using the notebook as a diary to vent her frustration with everyone else, particularly her sister. Despite the fact that Tsukasa is harder-working, her sister always seems to be more popular.
