One person chases the light and is seriously injured, while the other person stands in the darkness and shows his sorrow coldly.
The two confront each other, learn from each other, understand each other, and become each other's support for persistence.
Half-father and half-mother, they love each other and yearn for the future, but there is no future.
Purpose: Let go of hatred and prejudice, understand each other's past deeply, forgive each other, and reach consensus with love
