The introverted Lin Yi gradually grows close to her, only to discover that Xiao Ba is the company's prototype model and is facing memory erasure. Lin Yi awakens the power of emotions and leads the abandoned figures in a charge toward the headquarters. To stop the destruction program, Xiao Ba overwrites the core system with her own consciousness and vanishes into specks of light. A year later, Lin Yi lives alone, when her voice suddenly sounds in his ear once again.
