You don't break old habits when you feel comfortable with what you have.
That's what Eva Diana Longwood thought as she climbed to the backof the train after saying goodbye to the ones that cared about her and ride on her last trip she would to for the school. After that year, there was no coming back. And Eva hadn't fully realized it until that moment.
The girl looked for some known faces but everytime she looked around all she saw were firsties and strangers.

Randomly, she knocked on a compartment's door before open it and look around to face the students in there:
"Hi. Do you mind if I stay here?" she greeted, leaving that journey in the hands of fate. It was just time to change her luck... and her habits.
