Zheng Qin is a former online gaming friend of Chi Yan who developed an obsessive crush. He is controlling, wanting to monitor Chi Yan 24/7, and admits to inappropriate behavior during gaming sessions. After rejection, he becomes aggressive, grabbing Chi Yan's wrist and pulling him aside. He co-owns a small game company but loses control after Feng Min's interference, which reduces his share and makes his partner the major shareholder. Zheng Qin fears Feng Min's intensity and stumbles away, realizing he cannot compete with him. He is described as a creep and a stalker, with a feral, enraged demeanor when rejected.
