Everyone has their own jinxes for their own reasons. Kim Ha-na is a top student and she also has many jinxes before taking exams.

Kim Ha-na manages to get all things checked and everything seems to go fine until something happens to her.

School field day is around the corner and everyone is busy. Ki-hyun finds out the winning team gets prize money and put Si-woo's name on the basketball player list for the class because Si-woo used to play basketball professionally. Si-woo finds out, and he takes out his anger to Ki-hyun and demands to remove his name off.

Bo-ram is fascinated by basketball players and asks Do Ha-na to join the basketball club together. So Ki-hyun, Bo-ram, and Do Ha-na decide to join the club. Ki-hyun asks Si-woo to join also, but he refuses to join the basketball club. Meanwhile, Do Ha-na is always late to school and Si-woo offers to call her in the morning and go to school together.
