Teenagers are teenagers. They are displeased by their youth, not annoyed by the summer cicadas, not sad by the autumn wind, not sigh by the winter snow, are too lazy to notice when they are surrounded by wealth, and are not brave enough to face injustice. Just because they are teenagers.
Concept: The heartbeat of a young man is like the wasteland on a midsummer night. It can't be cut and burned. When the wind blows, the weeds reach the sky.
