- "I want to live again." When Zheng Xingran, a high school student, fell into the cold room again and again, this sentence beat his body and mind like a heavy bell every day, until Chang Ping appeared by his side unexpectedly. This man held a light for him, which was not very strong, and carefully led him forward step by step. "You can't die in the past, you have to swim upstream." Childhood trauma is a scar that cannot be erased, but there will always be someone willing to stop and slowly heal it for you, telling you softly that you can be reborn from the ashes like a phoenix. Under the oppressive and dim water, the encounter between Zheng Xingran and Chang Ping was accidental and inevitable. Growth and touching, suffering and experience, the life and love in their hearts all broke through the darkness and illuminated the water in an instant.
