In Kai's workspace, he was sitting while reading the patient paper. But his mind was occupied with thoughts about what they had been discussing. It's about the gangsters walked around the hospital.
"Maybe this is just a coincidence" Kai thought hard.
Kai thought hard about what they had talked about at lunchtime earlier. He wondered if Mike was the person that the gangsters were searching for. He also remembered that two days ago, on the way home, a gangster had asked him about a wounded man around his house.
And suddenly, Kai have a thought to kick Mike out from his house.
"Maybe this is my chance to kick Mike out of my house if I hand him over to the gangsters" Kai said with a happy face.
"But if I hand him over to the gangsters, he will not come to take revenge on me, right? Hmm...." Kai thought again.
