First of all, as recalled at the beginning of the film, the little girl was the "ugly duckling" who was not invited at the dance, but she framed a boy who invited him. In addition to the injury to the little boy, she also suffered a lot of damage. It is also mentioned in the second half of the film that the girl who grew up once confessed to several other friends that she was a fat girl when she was a child and had low self-esteem. We can also see that she is full of jealousy of her beautiful friends. and hatred.
Secondly, she repeatedly drew everyone's attention to the alcoholic boyfriend, making people think that he was the murderer. On the one hand, her jealousy was at work, and on the other hand, she might just want to blame him.
Also, she was not there for the first few murders, so she was most likely the murderer.
Fourth, if the murderer is someone else, why kill her boyfriend and her maid? It doesn't make sense. And her boyfriend cheated on her, her maid humiliated her, and her words as a murderer are well explained.
Fifth, I think everyone died in the end, the girl died in her boyfriend's arms, and the boyfriend had a nosebleed, maybe because he drank her family's wine and ate something from her family's poison.
Sixth, such an ending is quite unexpected. If it is revealed at the beginning, there will be no suspense. Because I have been thinking according to the picture from the beginning, I believe that the murderer is a little boy, and I just want to know how the murderer was caught in the end. But the ending really got me thinking about it.
Personally, I think the man who is dating frequently at the beginning of the film is not a grown-up boy, but an obstacle set up by the director. Because according to the judgment of the police behind the mugshot, it is not a face at all, and it is impossible to change a face.
Maybe the director just wanted us to guess, anyone could be the murderer.
