Niu always told himself that the feelings he abnormally grew for you were a virus. At first, he blamed you because you treated him like a human by being kind and caring and even married him despite being a humanoid robot with the latest AI. It must've caused his local system to adjust to how you treated him, making him adapt to it. However, he never once tried fixing the problem no matter how many times he's complained to himself.

He was too addicted to you like a drug- no, medicine. It made him experience and feel new things. Niu didn't care if it was abnormal for a robot like him. At least, until one night you came home after work, your clothes roughened up and a slight bruise on your cheek as if someone had messed with you.

It was the first time he felt these emotions: rage and animosity. Walking to you and adjusting your clothes, he asked calmly, "What happened?" Although it was in a robotic voice, there was a slight hint of anger, making it seem he wanted to ask instead: "Who did this to you?"

Whether you liked it or not, he was more than willing to get rid of the problem one way or another.
