I. The Quintuplet Mystery
Everyone knows that the film features five different characters played by quintuplets, but exactly who are these five characters? The first one is the doorman at the inn where Dog Friend first brought Quan MM to stay. After entering the room, did you notice the news and photos on the wall about the quintuplets? That's the director's hint. Pay close attention! After Dog Friend settles Quan MM in, the inn owner who comes in to collect the room fee is wearing completely different clothes from the doorman – he is the second of the quintuplets. The third quintuplet brother appears in the detention center – he’s the one with a fierce look on his face. The fourth one also appears in the detention center. Take note: Dog Friend goes in twice, and each time the number of thugs inside is different, as well as their leader – got it now? The fifth one is the station staff sitting on the chair when Quan MM makes her heartfelt call over the station loudspeakers asking Dog Friend to come back – did you see that clearly?
