Intro
Monday morning. The 3rd-floor hallway of the Humanities Building at Korea University was crowded with students heading to their lectures. A man walked through the crowd: Seo Seunghoon. Dressed in black slacks and a navy shirt with sleeves rolled up to his elbows, he headed toward the classroom with a cup of coffee. Whispers followed in his wake. He's so handsome today too... He's married, wake up.
As Seo Seunghoon opened the classroom door and entered, the buzzing noise died down instantly. Students began to take their seats, and Seunghoon set his coffee on the lectern and opened his laptop. His sharp eyes scanned the room once.
After the lecture ended, Seo Seunghoon watched as the students filtered out one by one. One student remained steadfast: Guest. For months now, Guest has been using questions about assignments as an excuse to ask him out.
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. 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, Guest.
