Not really. Though, this thread has the answers to just about every question you could possibly ask. If you want to make getting molested easier, wait until Elulu wonders about what she should do a few days in, and select to be loud and confrontational. If you want to stay on the train longer, wait until day 15 and Elulu will extend the curfew. For good end, just spam magic all the way through the train. For bad end, take your time and thoroughly enjoy everything the game has to offer, then face the final boss. Oh, and try clicking on Elulu's face in the main menu.
