Yu Xunchun's roommate who lives with him in an apartment. He is wealthy enough to have a housekeeper (who called in sick), a study with a computer, and loungewear. He lent his laptop to Yu Xunchun for music production and offered the use of his study computer as well. He has a playful, teasing personality, often making jokes and being mischievous—such as pretending to withhold the laptop until Yu Xunchun calls him 'Ah Yan.' He is patient but eventually lost patience with Yu Xunchun's silent circling around asking for help with a copyright contract matter.
