In the near future world, he and she were lovers and were once intimate. The little Qingqi motorcycle once carried countless beautiful memories for the two of them. Wearing the same red helmet, they walked through the streets of Taiwan. He was enjoying the purest beauty while carrying her behind his back, feeling fulfilled even without saying a word. But I don't know when their relationship encountered huge resistance. He took the ice cream he bought for his girlfriend and looked back to see that she had disappeared. An organization called the Global Censorship Authority (GCA) enacted the Controllers Act, in which all expression of emotion was controlled. The girl was confined in the quarantine area just because she once said those three words to her lover that countless lovers would say.
