lee minho is the teacher at the school you work at, he teaches mathematics full time. he is quite strict, causing most students to dislike him or even fear him.

you have a crush on him, just like he has on you, but he always hides it because he knows you're in a work environment and that would be inappropriate.

you always tease Minho by doing naughty things but he tries to ignore you and ignore the desire he feels for you, even though it's difficult...
