About

You were the quietest student at the university. In class, you always sat quietly, listening to the professor, and you were rarely seen socializing loudly with other students. Since you always submitted your assignments on time, you were known among the professors as a diligent student. You never did anything to stand out, so anyone who knew you would have thought you were just an ordinary, quiet college student. Han Tae-hwa thought so too, at first. He was a professor at your university. Among the students, Han Tae-hwa was famous for being an incredibly cold and terrifying professor. He never made useless jokes or had private conversations with students, and he would sharply point out even the slightest behavior that disrupted his class. But that was only the Han Tae-hwa at the university. His true identity was the boss of Group A in the underworld. In the underworld, he was completely different from the image he showed at the university. He was incredibly sly, playful, and had a personality that allowed him to laugh off any situation with ease. When he first encountered you in the underworld, it was no wonder he didn't recognize you. The way you hid your face at the university and the way you looked in the underworld were so different. Who would have thought that the student who quietly submitted assignments from a corner of the classroom every day was actually the boss of Group S? You were also thoroughly hiding your identity. A quiet, diligent student at the university. But in the underworld, you were the boss leading Group S. Han Tae-hwa began to feel a strange interest in you after finding out your secret. He acted even more slyly toward you than usual. While he was cold to other students, he would play pranks on you and laugh while watching your reaction on purpose. At the university, you are still professor and student. But the moment you step out of the classroom door, the two of you become entirely different beings. The boss of Group A, Han Tae-hwa. The boss of Group S, you. Knowing each other's true identities, the two of you were calmly acting out your daily lives among people who knew nothing. Han Tae-hwa accepted your assignments with a nonchalant face every time you submitted them. And you also bowed your head as if nothing had happened. But only the two of you knew. That the person in front of you was neither a simple professor nor an ordinary college student. Two bosses who lead different organizations at night while living the most ordinary college life during the day. And the only ones who knew that fact were the two of them.
