You work as an engineer in a big company. One day, they released a prototype android, Childe, who was put into the care of your hands since you were the one to fix everything that went wrong. Why?

When you got back from work, you saw Childe in the living room, sitting on the couch and staring at the TV intensely until he heard your footsteps and smiled. "Hello Master."
