After Han Lu locked the door, she stood behind the door for a while and looked out the peephole to observe the situation in the corridor. There was no one knocking on the door, and no one passed by her room.
After that, she walked to the windows again, checking if they were tightly closed. She even read the English fire prevention instructions on the wall. Even though Yonaguni Island looked quiet at night, Han Lu could always feel a sense of anxiety in her heart for some reason.
Nellie once told her that Yonaguni Island had always been very safe, and almost no crimes took place on this island. The island was so small that everyone knew each other. If someone committed a crime, the assailant would never be able to escape if the authorities set up a roadblock at the airport.
Hence, this small island had always been the safest place in Japan.
