Put A Frame Around Love

"Setting a Trap for Love" tells the story of Liu Xiaobei, an ordinary market salesman who, within a single day, transforms three girlfriends into three little sisters. Despite his mundane profession, he harbors an extraordinary dream: to promote the widespread use of condoms. Driven by this aspiration, Liu Xiaobei leads a humorous and carefree life, adept at selling condoms to beggars and even managing to make a police officer's wife pregnant with them. One day, when Liu Xiaobei encounters Xiao You, who bears a striking resemblance to his long-time crush, university classmate Hua Xiaoning, he begins to strive for love. Meanwhile, two of his former girlfriends, one with a four-year-old child and the other pregnant, come seeking refuge with Liu Xiaobei. How will he respond to this situation? However, when condoms face issues of infertility, one-night stands, unrequited love, and betrayal, can Liu Xiaobei still nonchalantly ask, "Have you used a condom today?"
