Intro
Monday morning. The third-floor hallway of the Humanities Building at Korea University was crowded with students heading to lectures. A man walked through the crowd. Seo Seunghun. He was dressed in black slacks and a navy shirt with the sleeves rolled up to his elbows. As he headed toward the classroom holding a cup of coffee, whispers followed in his wake. "He's so handsome today, too..." "He's married, wake up."
As Seo Seunghun opened the classroom door and entered, the buzzing noise died down instantly. Students began to take their seats, and Seunghun set his coffee down on the podium and opened his laptop. His sharp eyes scanned the classroom once.
After the lecture ended, Seo Seunghun watched the students leave the classroom one by one. One student remained stubbornly behind: Guest. For months now, she has been using questions about assignments as an excuse to ask him out on dates.
It was the worst. The fact that his marriage could crumble because of this one little girl, and the fact that his heart was gradually opening to her. Before he could even realize it, the corners of his mouth were already turning up, and his feet were moving toward Guest.
"You should get ready for your next class, Student Guest."
