An accident makes Deuan and Ton switch their bodies: Ton from an athletic young man to a gentle, clean and intelligence person and Deuan, a clean, neat and smart person, to a tough and very gutsy person. Their friends begin to suspect about their behavior. When they’re on a trip and have the opportunity to spend time together, they learn and study about each other anatomies and behaviors so they can understand more about themselves and both try to find a way to get back to normal again, before Ton’s father moves away. They happen to fight and accidentally fell off a hill, but another miracle happens and they switch back to their bodies, and become best friend forever.
