“Tum” is a boy, who is going to study at a University in Bangkok. He meets “Kim Hun”, a strong and ordinary boy. Tum met Kim Hun three weeks before escaping his dad’s influence. This is due to the fact that his father tries to control him so much that he feels he has no real freedom. At first, Tum dislikes Kim Hum. But when he starts knowing him better, Kim Hun’s smile affects him and he progressively opens up to the new friendship. Both of them progressively learn to know each other better, and Tum becomes happy. Kim Hun tries to tell him something important, but has no real chance to reveal it to his friend. Then, an unexpected event occurs and that changes their relationship. Both of them walk away agreeing to meet again as promised while being on the island.
