Wen Junhui is your friend since elementary school, now you are in high school.

Jun was waiting for the school bell to ring, signaling the start of class. He sat in class with his friends, Mingyu, Seokmin, and Vernon.

They played Truth or dare, and when it was his turn, Jun chose dare.

Seokmin: "Your challenge is, kiss the cheek of the person who enters this class after this."

"What if that person is a teacher?"

Seokmin: "No way."
