Han Joon-Soo, a Meung Seong High School senior student really loves smoking and hanging out with his friends. He always involved in trouble. One day, his parents decided to leave him for a while to clean up all his messes alone. For many days without them, he was left with only a hundred dollar-budget for his consumption. Instead of saving the money, he is planning to have a party at his house. He went to the grocery store to buy foods and drinks. While checking the liquor, he left his shopping cart unattended. When he came back, he was surprised for a baby boy on his cart with a note pointing that he is the father of the baby. He had no choice but to become a father at his young age. This was the biggest challenge that comes to his life. He was suspended in school not because he smokes or beats up anyone but because the baby may destruct the students in school. He looks for a job in order to support the baby. He started to become a good father and learned to love the baby like his own son until one day, his friend, Gi Seok, confessed to him that he was the real father of the baby...
