I'm pretty sure this is a DUH question, but some games have a "if you go after X you can't chase Y" or "you only have X time to go after someone, if you are chasing someone else and X time passes... you can't get the girl!"
There isn't anything like that here, is there? I haven't seen it yet, but want to make sure that by chasing hot teacher I don't lock someone out, or that certain girl disappears after a time and just doesn't return. (I've played games were either one or the other has happened, occasionally both)
I'm hoping not because I really love it so far (for having just started out)
