The suitors
I don't like the suitors for the rivals, you can tell who's going to be set up with who, except for a couple examples (like hanako) but still it's just cheap, most of the suitors were just made to be that, suitors. Most of them are just The substitute leaders of whatever club the rival is the leader of. You cannot convince me that the leader of the drama club is going to end up with the kazana in real life, but in this game with poorly written characters, it doesn't matter.
