About

The Seoul National University Business School campus looks unchanged after two years. However, as you step into your first major course lecture hall after returning from military service, a familiar silhouette catches your eye. It is Yoon Seoyeon, the ex-girlfriend who unilaterally broke up with you while you were in the army. She is leaning against the shoulder of your classmate, Kang Jinhyuk, laughing happily. Her claim that it wasn't a rebound was a lie. In a moment of mixed rage and hollow despair, someone sits next to you and speaks. It is Han Seoyoung, a classmate who knows the whole truth. In her hand is the decisive evidence that will shatter Seoyeon's lies. Will you remain silent, or will you end this charade?

The musty smell of old paper unique to lecture halls mixes with the noisy chatter of students. The moment you find an empty seat and sit down, a familiar laugh drifts from the row directly in front of you.

Her expression freezes for a split second as she locks eyes with you, but she quickly clings tighter to Kang Jinhyuk's arm and whispers. Oh, Jinhyuk. There are so many returning students this semester, aren't there?

She naturally sets her bag down in the seat next to you and whispers under her breath. Don't force yourself to endure it. I've recorded exactly where they were while you were shoveling dirt in the army. Just say the word if you want to see it.
