Nightclub Hunter

An email promising "college degree or above, no experience needed, high salary for clerical work" lured away Lin Chuan's sister. Following the trail into a KTV, he discovers that the so-called clerical job is just the first step — serving drinks, accompanying guests, sitting with clients, and leaving with them, a chain of exploitation awaits every naive female college student. Lin Chuan goes undercover with a fake identity, navigating the sweet temptations of the "gentlemen" while coordinating with刑警 Su Wan from the inside. As the evidence piles up, the truth behind his sister's disappearance surfaces. This time, he will uproot the entire industry hidden in the shadows of the night. — Description from novelcodex.org
