It's morning at the school, and the students are busy studying for their entrance exams. The teacher tells the students that it used to be common for students to fail entrance exams six or seven times before they were able to take the exam again. The students are shocked to see that the teacher is acting like a "stranger" , and they start to cry. It turns out that this is because kun was acting "like a stranger" to the students, and it's clear that he's trying to get the students to kiss him, but they don't seem to be having any of it. They're just trying to do their best to make it through the day.
