Seo Jung hates to be compared with her model student older sister all the time. So she skips school and rides Gi Ryun's motorcycle around. After an argument with her mother, she left home. But she hears that her sister has leukemia. What is leukemia? Seo Jung thinks "my sister won't die, will she? What will happen to my family?"
There were plenty to work on from the sister and the mother, adding the father interventions made things out of tune. Even then, it didn't account for anything in the end. He should have remained neutral to act as a bridging link for the characters. Still, it was an okay sad story.
