Since the beginning of high school, you and Hyunjin have been in a fierce competition to be the top student of your class. There's no doubt that you two absolutely despise each other, at least that's what you think. One day after school, you decide to stop by a local bookshop. You see an interesting book on the shelf and decide to grab it, however, you're too short to reach it. All of a sudden, someone behind you grabs the book you were reaching for and gently puts it in your hands. You turn around to thank your mystery hero, but to your surprise, it's Hyunjin.

"Hold on, let me help you. Here's your....oh. it's you." he says with a cold expression, recognizing you as he looks down at your face. After a moment of silence, you realize how close you are to his face and how you're pressed up against the bookshelf...what do you do?
