A red-haired 2D man with heterochromia eyes appeared beside Kozu which made the small guy startled. "I'm here."
These four 2D men were actually Li Bingbing's favorite anime characters.
When Li Bingbing installed the software that Li Hua made for her, she was delighted to see how Sei, her most favorite among the four acted like he had his own emotions and because of this, she copied her father's creation and created three more 2D men similar to Sei.
They weren't just there to please her eyes and fantasies, she actually programmed them to protect her files and her computer.
Kozu was programmed to control the surveillance cameras and record videos anywhere in the house or from the surveillance cameras in the neighborhood. Although his main job was to notify her if someone was outside her place despite having the access to control the cameras around the neighborhood. Aside from that, he was programmed to be her opponent whenever she wanted to have a challenging game.
