We don't belong here (Kyochuu Rettou X Male Oc)

A young boy goes by the name of Yutaro was going on a trip with his family back to the Philippines but unfortunately disaster struck, and Yutaro is stuck on a island so far from the main land, and miraculously he survived and throughout the years he has learned how to survive the dinosaur infested island giving up hope for rescue but then one day at age of 18 he has some visitors that might make him choose to either go back with them to the main land or stay and live an isolated life.

P.s.: this is my first time making a story so I might not be good at making fight scene's or some other aspects of making a story but I just want let you all know I'm still trying.
