Johans has never had a normal life, from the moment he was born he grew up eating from insects to animal raw or not just to survive in this harsh environment. Even all that Johan was already 188 centimeters at only 15.
So when Johan hears the announcement of the soldier all he thinks about is a warm house with full of cooked meat, so without a second thought Johan decides to go to that soldier. When he opens the door he sees that almost every family are sending their children, so he swiftly follows those kids to reach the central, on the way Johan sees his bullys, who bully's him almost everytime he sets a foot outside. The bully's were all same age but 2 years older than Johan, even tho Johan was much taller than those kids but Johan was as skinny as a stick. Johan takes the longer route to avoid being seen by his bully's so by the time reaches to the announcer it was already full of folk and the line was way far back.
Johan waits 30 minutes until it's his time to be registered, the soldier asks his name and age, which Johan answers "Johan, 15 years old" the soldier asks his "are you sure you're 15? you are very tall for your age" and so soldier gives him a number tag #35. he was not the last kid there there were total of 38 children there to be recruited. So all the kids get on a big truck on set their tail to the main city. In Johans mind it was all about starting a fresh new life.
