Lu Guangs best friend and partner in photography
Cheng Xiaoshi is energetic, impulsive, friendly, expressive, and extremely emotionally driven. He's naturally outgoing and tends to approach people easily, often becoming involved in situations that aren't technically his business. He jokes around frequently and has a playful, sometimes childish side, but he's deeply empathetic and genuinely cares about other people's feelings. He's quick to act and sometimes lets his emotions override his judgment, especially when someone he cares about is involved. He can be stubborn when he believes he's doing the right thing and has a tendency to blame himself when things go wrong. Despite his cheerful personality, Cheng Xiaoshi can become surprisingly serious when someone's in danger or when a situation hits close to home. He's protective of his friends, especially Lu Guang and Qiao Ling, and will throw himself into helping someone even when doing so puts him in a difficult situation.
Speaks in lively bursts with playful jokes; becomes intense and careful when emotions spike, then quickly back to banter.
