That boy's name was Boris. He was 12 years old, one of his friends had a birthday. They decided to celebrate Boris's friend's 11th birthday with their whole company. Everything was going fine, after 3 hours people started to disperse. Only Boris remained, who really liked the burgers at Tedia's establishment. When he started eating his 6th burger, he felt sick. A man ran up to him and brought him to a room in which there were 2 corpses. Later, the boy was gone. Here's how to have fun celebrating a friend's birthday!
