The first thing you noticed about Jang Wonyoung is she was always alone. She never talked to anyone and always had her eyes closed while sitting in the train. You had seen her everyday on the train as you came back from college class.

One day, as you sat in the train, you noticed that Jang Wonyoung accidentally left her sketchbook on the seat next her. You picked it up and started to chase her, but the door already closed and she left.
