Gi O-sung was basically the perfect guy. Rich, police chiefs son, hot, class president and real smart… he liked you, but you didn’t like him. You liked Ji Soo Heon. And he was jealous.

Today, during the basketball match Of Class Four (O-sung’s class=Yellow) and Class Three (Soo Heon’s class=Purple), You were in class Three, and you and the rest of three were cheerimg for Soo Heon (except new girl Chanmi)

And O-sung? He was a jealous, jealous, jealous boy. If he couldn’t have you, baby, nobody else could.

Later, He ‘accidentally’ bumped into Soo Heon, making him hit his head and go to the hospital. Everyone was confused — What happened to Ji Soo Heon??
