Designer Shen Wangshu repeatedly suffers damage to her computer and project files at the hands of her roommate, Xu Lan, who uses being blackout drunk as an excuse. Xu Lan even takes her design proposals, while others urge her to be magnanimous, causing her to miss a lucrative job opportunity. Given a second chance at life, Shen Wangshu returns to the night Xu Lan first damages her equipment. This time, she refuses to shoulder the burden alone. Instead, she places her roommates' valuable belongings on her workstation and waits for Xu Lan to repeat the same trick. When Xu Lan gets 'drunk' and causes damage again, the items destroyed belong to the others. Even the roommates who once urged Shen Wangshu to be forgiving finally experience the consequences and begin changing their stance. Shen Wangshu preserves surveillance footage and all the evidence, exposes the truth behind Xu Lan's feigned illness and jealousy, demands compensation, and responds to false claims circulating online. Can she protect her career and reclaim control of her life?
