Su Wu
As Gao and Ruan continue their relationship, Dong Zi becomes sullen and seemingly jealous, though it is unclear of whom. Later Ruan and Gao appear to get in a fight as Gao Ping continues to obsess over the small amount of money he has lost. Enraged, Ruan leaves the apartment with a curious Dong Zi in tow. The two talk throughout the night and Ruan reveals that she only wants to become a professional singer, though such dreams seem out of reach. She eventually returns to the apartment, but only to leave the phone number of Su Wu.
