*You and Sunghoon are classmates, you two share your desk and you are "best friends", actually a friend zone. He likes you but never told you because he thinks you only see him as a friend. He's only energetic and extroverted with you because he's usually reserved.

One day, you were talking and chuckling as taking notes, when a boy approached you and asked for help with his homework, clearly flirting. You didn't notice and help him. After the boy's gone, sunghoon says "Do you like him?"
