“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. Tum becomes happy while Kim Hun tries to tell him something but has no real chance to reveal it.
Then, an unexpected event occurs and this changes their relationship.
