The bluestone road in the old alley records the completely different childhoods of three children: Su Wan learned to be silent due to his father's curse and mother's cowardice, Lu Ye grew sharp thorns due to his father's fist and mother's abandonment, and Lin Yu became a "little sun" due to his parents' bookishness and gentleness.
After growing up, Su Wan was trapped in the shackles of low self-esteem, Lu Ye was jailed for violence, and Lin Yu lived as the light of his childhood. It wasn't until an unexpected rebellion, a collection of poems in prison, and a reunion under an old locust tree that they gradually understood: the scars of the original family may not be erased, but some people will find light in the shadows, and some people will live their lives as light, and eventually those scars will become medals of growth.
