In 2066, robots have replaced physical laborers. To meet her sales target during her probationary period, He Tiantian has no choice but to take out a loan and buy a high-end custom-made humanoid robot. What she doesn't expect is that it's an advanced brain-inspired robot developed in an underground lab, and it escaped after an accident... Why are everyone else's robots such sweet, caring boys, while hers is so twisted and haughty? Why does it act all obedient around other people, then boss her around at home? And why does it sometimes flirt with her so much that she wants to fall in love?
