The two-way redemption of a talented pianist with broken wings and a cold-hearted guitar girl. The once-famous piano genius suffered a tragic change and locked the black and white keys with his own hands. The cold girl who walks alone with a guitar in her arms hides her thoughts in the sound of the strings all year round. Two hearts trapped in darkness slowly come closer. They healed each other's pain over the years and became the only light in each other's lives.
