Harumoto Shu has been working at a game development company for 5 years. Recently, she was appointed as the person in charge of a large-scale game project jointly produced by China and Japan. When she was full of enthusiasm for her future work, she found out that the person in charge of the Chinese company as a client was actually her ex-girlfriend Lin Dongyu, whom Shu had unilaterally said goodbye to during college. After the two separated, Shu did not start a new relationship but buried herself in work. She did not disclose her sexual orientation in the company or at home, but now she is shaken by the sudden appearance of her ex-girlfriend. On the other hand, Dongyu has always hated Shu for being dumped without telling her the reason, so she, who is in charge of the project, asked Shu an unreasonable question. What will be the ending of Dongyu who intends to take revenge and Shu whose love is rekindled?
