When I was young, I fell in love.
I loved her from a very early age, and she was like a big sister to me. Her mother died when she was little, and her father was always working.
But, she went to college, and had to move.
I confessed my feelings to her, but the train's noise took her answer away with the wind.

A few years later, I went to university, and forgot the events that happened then. I had trouble finding a job, and my brother got married and moved to Hawaii, so I decided to go back to my parents' house.
However, there was something I didn't expect...

To meet with her again, under the same sky, while she smiled as always.
