Jealousy and tears of the doll are all manifestations of the doll's humanity. Although the doll is just an artificial person, she has feelings. I don't know if you have noticed, when DOLL shed tears and the hostess wiped her tears, it was DOLL's perspective. In other words, the doll began to have human feelings and was no longer a robot without feelings.
In my opinion, dolls are lovers. The painter and his wife had a good time. But the departure of his wife made the painter particularly sad, and the lover replaced his wife. A painter treats his lover like a wife. He regards his lover as life. So he thought he was reborn, his clothes changed from black to white, and his favorite background changed from bright red to white. He fell in love with his lover. A lover is no longer a substitute for his wife, but a lover with white characters on a red background. However, the painter found himself immersed in this red and white color, and he couldn't tell whether he liked his wife or lover. Because the lover has no feelings, it is very painful (a painter recalls his wife's scene, and his wife's behavior is inversely proportional to his lover's behavior in front of him). Finally, he painfully chose to commit suicide. The lover was tagged (there was a shot of a lover with a tag around his neck after the painter died) and sent back to the place of manufacture. According to the painter's wishes, the manufacturer made her a lover wrapped in red. Sold it to the hostess as a doll.
Stimulated by the jealousy of the hostess, DOLL finally remembered the past (the red umbrella represents the painter's story) and shed tears. The hostess wiped her tears. The doll finally escaped and became a stripper.
A stripper is a passionate and happy dancer. In the MV, the cheerful and enthusiastic dance of strippers is symmetrical with the expressionless dolls and lovers from time to time. Artificial people have feelings. She danced and told people about her experience.
Some small clips can prove that the three characters belong to the same person: for example, the stripper lying at the beginning of the MV just woke up and looked up and saw a red lantern in the dark. The stripper's memories of the past are mixed with red umbrellas, bar codes (bar codes are the same as the lover's neck) and the jealousy of the hostess.
