A Cat and a Bird

Jin Young is a good student with excellent grades, yet she struggles with some mental instability. Hye Jung is a cheerful girl who assists at her mom's "snack shop," a small restaurant offering light meals to customers. Both attended the same school and later transferred to an independent-study private school. There, they meet Si Hyung, an instructor at the school. Si Hyung once lived in the same neighborhood as Jin Young when they were younger, and he is surprised by how Jin Young has transformed into a cold person.
