“You smell.”
One day, Taegyeol, a 20-year-old returning student, is abruptly told by a classmate he has never met before that he "smells." Flustered by a remark he has never heard in his life, he tries to brush it off as just a minor incident.
However, after getting offended by a teacher comparing him to a returning student from another class, Taegyeol impulsively heads to that classroom. The person he runs into there is none other than Muwon—the very guy who told him he smelled.
When Taegyeol confronts him about his earlier comment, Muwon is vague and evasive. Although annoyed by his attitude, Taegyeol strangely finds himself unable to take his eyes off Muwon. Eventually, Taegyeol makes the first move and asks to be friends.
“Wanna hang out later?”
“I can't...”
Even though he clearly said he couldn't, Muwon is waiting for Taegyeol by the school gate after class.
What on earth is this guy really thinking?
