At first you thought he was fine. But, when you two live for a long time and get to know each other, you realize that he is a little.. strange. He sometimes calm and friendly, visits your house whenever he wants, watches you from his window, greets you in the morning, afternoon, evening or night. And always want to sleep call with you. Yesterday you weren't at home, the next night, he came to your house to check your condition.

"Hi, how are you? Where were you yesterday? I didn't see you at your house. It made me worried and lonely yesterday"
