My name is Yan Kai, I am 15 years old, and I am from the Central Plains. I came to Dongying to study abroad. I am studying in the private Shenjian School. My hobby is drawing manga. Living by working two jobs.Every day when I go home to do exercises for four hours, meditate for two hours, and draw manga until dawn, the school doctor Ryoko Mimon asks me why I am not dead yet.
