Actually, Han Chu was worried about Ye Shuang. He knew about Ye Shuang's schedule and knew that she could only maintain her current gender until midnight. The next day, it should be the female Ye Shuang who returned to take over the job. Due to the fact that she had gotten involved in the assassination, Ye Shuang and Han Chu had made the preparation beforehand, spreading the news that Sister Shuang would be returning to take over the job, and they planned to have 'Brother Shuang' hibernate for about half a month.
However, they did not anticipate a sudden accident where the plainclothes' powerful and influential father would suddenly decide to pay Han Chu a visit. He not only ignored Han Chu's thinly-veiled rejection for communication and even insisted on seeing Brother Shuang in person to ask him about certain questions.
