We all come into this world with similar gaps, thinking that when we meet each other, we will make a complete circle. But later I realized that similar people can only see each other's scars, but they cannot be each other's salvation. This encounter pointed to separation from the beginning.
Concept: Two teenagers with similar scars meet in loneliness and say goodbye as they grow up. They are each other's light and each other's regret on their way to growth. They eventually learn to reconcile with the past and move toward the future with memories.
