A skinny boy in elementary school named Poong has a lot of fears, even running away from a little mutt, but he’s also very playful. He has a crush on a girl named Rang who’s in the same class as his and also is the daughter of a vegetable vendor in his neighborhood. One day, Rang sees Poong get picked on by the school bully and his twin sidekicks. Poong becomes devastated. But then later, he coincidentally sees The Incredible Hulk playing on TV, and feels a weird sensation run through him. A few days later, Poong stands on top of a slide and jumps off to find not a single scratch on his body. From this point on, he feels invincible.
