Ten has always been an independent, somewhat introverted person who enjoys the simplicity of his routine with his friends, Yuta, Jungweoo, and Jaehyun. But one day, out of nowhere, a mysterious letter arrives in his locker, signed by the name "Jeong" written in delicate script. Intrigued and excited, Ten reads it, and he finds that it's an intimate, thoughtful letter-filled with insights about his life, his passions, and his dreams. It's almost as if the writer knows him better than he knows himself. The letter ends with a simple message: "For now, good-bye my angel."
