Kris Wu is a new teacher in COED Public High School, where the students are mostly the worse gangsters in the town. It's a small school in a small town, where the capacity of people is barely 500 people. Kris' class consists of eleven students: Tao, Jongin, Sehun, Xiumin, Lay, Chen, Luhan, Chanyeol, Suho, Baekhyun, Kyungsoo. He learns the difficulty with his students, until an accident between Kris and his two female co-workers and their students happen. Will this bring any more troubles for the already troubled teachers, or will this make the students less rude with their teachers?

The house party where Kris was heading was in action when the timid teacher arrived. He never heard about this kind of "council meetings" when he was at the university. The house was raging from loud music and the neon lights were lighting up the street. Kris was merely taken aback when his superior teacher, Mr. Lee Sungmin waddled out from the front door, already tipsy. He was helding his phone and mumbling to himself.

"I gotta call-hick! My wife" he mumbled and in the next moment he was lying on a garden bench in the front yard, on his thumb like a baby. Kris rolled up his nose in confusion and just shook his head, hoping it was a bad dream.

He walked up to the front porch and he saw his good friend, miss Jessica standing in the hall sipping on a drink and moving slightly to the beat of the music. Kris hesitately walked up to her, considering her sober enough to explain it. Jessica was fast enough to recon Kris' appearance and she turned to him with a welcoming smile.

"It's nice to see you showing up, Mr. Wu" she said in a gentle voice and smiled brighter.

"What's going on?" Kris was expecting anything, except that! He would probably await a nice decent dinner and some wine, but not a hardcore, college-like, roof-breaking house party.

"You'll get used to it. It's a small town and people here are still young, even as teachers. We just want to relax some and get our rage out here" Jessica explained, shouting over the music. 

"Is it normal?"

"It is regular... We have our frontier, but not today... We are expecting to win over the teenagers! They are a party breakdown ahead" Jessica said and in the next moment, the whole house broke out into a loud scream. They threw their fists into the air and shouted their lung out. The music turned up even louder and the teachers went crazy! Dancing ridiculously, pooring booze down their throats, passing out drunk on the carpets, leaving Kris dumbfounded at the door.

These are the worst teachers ever... Challenge accepted! Kris thought.
