Bang Yongguk, 22 years old, a man with a messed up life and more irritating job. Yongguk worked at a high school full of average looking high schoolers. He grumbles and puts up with all the noise, scrunched up paper balls thrown at him (Especially 'love notes'), and the bland tasting coffee.

To be truthful, he hated his job. He hated it with all his heart. Heck, he would've quit his job and march away proudly; chin up, a smirk on his lips. There were so many other jobs that Yongguk could get that were higher paying and didn't have bad coffee. But he kept his job because of one student; and that certain student was named Choi Junhong, who was more likely preferred to be called Zelo.

Choi Junhong, 16 years old, a boy with a cute toothy smile which causes all the girls (And boys, ahem, and also a certain teacher) to squeal over. Zelo is a freakishly adorable (And freakishly tall), intelligent, well behaved student that any teacher would wish to have in their class. Yongguk adored Zelo. He loved the candy floss pink haired boy, although he was only at the age of 16 (A six year age difference). Yongguk didn't care though. It wasn't that much of an age difference… Right?

Wrong. Yongguk swore and beat himself up for falling for the adorable young boy, even though he didn't even know the other's feelings in return. He considered himself as a e; a ert for having those wet dreams about him, and a disgusting, vile, creature that doesn't deserve to live on planet Earth.

But what happens when the young 16 year old boy asks the frustrated teacher if he had any plans after school?
