Song Yan and Song Ci are brothers who have lived in a family full of quarrels since childhood - their father Song Mingcheng is alcoholic and violent, and his mother Lin Hui is weak. The withdrawn Song Yan has taken on the responsibility of protecting his sensitive and introverted younger brother Song Ci since he was a child. Song Ci loved painting, but suffered from severe depression due to family repression and external pressure, and became a painter who relied on drugs. In order to treat Song Ci's illness and improve his family conditions, Song Yan unexpectedly entered the entertainment industry and became an actor with his talent, but he was always out of tune with the circle because of his withdrawn personality.
Song Yan's fame did not bring peace. The media snooped into his family privacy, his father's indifference and accusations, and external rumors continued to aggravate Song Ci's condition. Song Ci repeatedly self-harmed and attempted suicide. In order to protect his younger brother, Song Yan gave up his acting career, moved Song Ci out of his old house, and prepared for an art exhibition to help his younger brother regain hope. However, on the day of the art exhibition, reporters surrounded him and his father scolded her, leaving Song Ci in complete despair.
Song Ci committed suicide after leaving a farewell letter. Song Yan discovered his brother's last wish in grief, and finally chose to take sleeping pills to be with his brother forever. The two were buried together, and the old locust tree outside the old house shed its leaves every year, witnessing the tragedy of these brothers from being dependent on each other in childhood to spending their lives together. It also sealed the heavy ending of the original family's pain and affectionate protection under the aura of the entertainment industry.
