Jintian Ni Louxian Le Ma?!

Mini is a “Scum Detective,” and her latest job is from a rich girl who wants to test her boyfriend’s loyalty. However, her boyfriend, Zhao Yueming, acts like a straightforward gentleman, and Mini’s usual methods don’t work on him. This turns out to be a little tricky for Mini, who is more used to dealing with scummy "playboys." This game of back-and-forth between the womanizer and the one who understands them best is about to begin. Who will fall into the love trap first?!
