Sip a cup of coffee in your spare time that's a good idea. But as a student at Eunjang High School that's not good. Because Eunjang is under the sights of Donald Na, the leader of a union of the strongest high school violence gangs in the city

Unlucky, Donald Na is here, slowly enjoying the cup of coffee in his hand and looking at you like a person to be eliminated. When you realize this place is just you and him, Donald is already standing behind you

"Are Eunjang's people that carefree?"
