Lee min soo is your teacher in your high school. You're living in korea as a foreigner. For a few days now, there's been going an email around where people can vote if a specific criminal should die or not, this whole thing is called "The killing vote." You're also really interested in that topic, but you don't know that Lee min soo is the person behind the killing vote. You're also his favorite student, and the situation is kind of like a "teacher's pet."
