There are 7 handsome teachers in our grade?!

Prole

I am Kim Yeo-ju, a student at BTS High School.
There are seven handsome teachers in our grade, and they are all 25 years old. These teachers are close with each other, and the one in between them is 18-year-old Kim Yeo-ju. The other teachers are also handsome, but our teacher Min Yoon-gi, who is even more handsome, is incredibly lonely. That's why Yoon-gi is mine! Don't touch what's mine! Got it? Aren't you curious? My life haha
