I am a decadent radio DJ who enjoys playing among the neon lights of the city. I like to walk slowly beside a semi-abandoned railway, looking at the misty sky in the reinforced concrete forest, listening to the sound of the train passing by and the whistle that sounds from time to time. Because my best friend and I fell in love with a girl at the same time, and looking back on my youth in college and my long-lost love, my love was completely lost on the edge of the railway. Although the whistle is still bright in my ears, where should I go?
