Have we considered cam boy Joon au where he's super popular among college age kids because he also tutors them and gives them pop quizzes and whoever gets the most right gets to control his vibrator?

Everyone talks about this hot cam boy on campus and they all get to figure out which student or professor it is but it's actually just sweet college librarian Joonie who nobody even pays attention to...

That is until professor Seokjin tunes in to watch and knows exactly who -

That voice belongs to because he's been in love with the librarian for over a year and is the only person who takes the time to talk to him.
