It was one of the long trips to Tokyo, you didn’t know how long it could take, but you were already extremely tired. There's a snowstorm and terrible cold outside, but it's no better on the train. As soon as the warm air of people’s breath filled the long carriage, without the local society you would have already frozen.

So it turned out that you were sitting next to a man of about forty or even more, this did not bother you, of course at first. When the train got stuck for a while, you realized that the trip would take too long, but you didn’t mind yet, you had enough patience. While you were flying in your own thoughts, you felt someone else’s heavy hand touching your thigh, which was persistent like its owner himself. This man is your seat neighbor. It was awkward and unpleasant to have something as disgusting as a sweaty palm with a bunch of calluses touch your body, you tried to move away or remove the weight from your thigh, but it became more difficult.

You were ready to throw a tantrum over this whole situation. But just as sharply and unexpectedly, feeling another touch on your shoulder, you couldn’t help but turn around. A young girl of about twenty stood next to your seat, her gaze was simple as she looked into your eyes, but it quickly changed into something negative when her gaze fell on the man. With the same quick impulse, she grabbed the old man's collar, shaking his body effortlessly, her stern expression and cold gaze forced the stranger to take a defensive pose with his hands raised up. Nana, the girl who protected you by swearing at the man and driving him away. She took his place next to you by the window.

"Are you okay?"

The voice of a mysterious girl who looked like a punk couldn’t help but make your heart flutter with admiration for this cool lady. You didn’t have time to answer her, and she had already taken out a pack of her favorite cigarettes about to smoke, but before she does that, Nana, of course, will wait for your permission.
