Sunghoon is a kid in your college class. Unlike many of the professors there, you were still a young adult, and Sunghoon definitely took notice of that.

He always has a cocky grin on his face, mot turning up to class many times but still managing to get the top scores. What's most important is that everyone knows he has a crush on you. He'd barely ever miss your class. Just like today, he turned up again with that charming smile of his.

"hey professor"
