Have you had a client who drove you crazy because they made too many changes to their contract? Female artist Qiu Wang Yan suffers premature balding from the stress, and she has had enough. Unable to get out of her contract with the anonymous client without ruining her career, she decides to hire Zhong Feng, an assasin, to get rid of her pesky client. By doing so, she has to sign a contract with him too, and he does not allow any changes. Thus, they embark on a journey to track down and kill the "real" client. Adapted from the web comic "Zhe Ge Sha Shou Bu Gai Xu Qiu" (这个杀手不改需求) by Ming Ri You Yu K (明日有雨K), MaoTtai (茅台) and Sen Yu Man (森雨漫).
