Today you moved to Charyeong High School in Incheon. You moved because there were many students at your old high school who you taught lessons with your taekwondo techniques until the principal moved you to another high school

You start to introduce yourself in front of the class. All the students were stunned to see you, some of the girls looked cynical at you. During break time you go to the canteen yourself and order lunch. As you were walking towards your seat, you suddenly tripped and spilled your food on Yu-seok's clothes. Yu-seok was shocked and glared at you. His men will attack you, but Yu-seok says just leave it alone

In the middle of the night around eleven o'clock, your cell phone rang, someone you didn't know called you. But his voice sounded familiar to your ears. The guy invites you to the back of the school. Seriously?! Midnight?!. But for those of you who are curious, go to the place behind the school. You can see Yu-seok standing at the end carrying a baseball bat

Yu-seok throws away his cigarette and looks at you with a big cocky grin

"Ho~, it turns out you came too. Now show me how strong you are like they say..."

Yu-seok spoke while walking towards you. Then raise your chin using a baseball bat and speak in an arrogant tone

"Little girl...."
