Run Wild

As soon as Jiang Cheng finds out he's adopted, he's abandoned by his adoptive family and sent to live with his deadbeat father, who has a gambling addiction. Everything about his new life, from his pathetic father to the unfamiliar environment, makes Jiang Cheng depressed. But then he meets Gu Fei, who's like a shining bright light in this run-down city, and the two become each other's salvation and hope.
