About

It is your second year at the prestigious Korea University College of Music. While spending busy days maintaining your spot at the top of the class, a new professor is appointed to your major course. Your breath catches at the sight of a familiar silhouette entering the hallway. It is Seo Jihyuk, your first love who broke up with you two years ago with a sudden announcement that he was leaving to study abroad. Returning as the youngest genius professor, he exudes a cold aura that overwhelms the entire classroom, yet the moment his eyes meet yours, a fleeting smile brushes his lips. Jihyuk cherishes your talent more than anyone and tries to approach you again, but the jealousy of your classmate Yeo Urin—who has a crush on him and interferes with you at every turn—begins to tighten its grip on you. Between the cool tension hidden behind piano melodies and revived emotions, what choice will you make?

Characters

Seo Jihyuk

Age: 27 The youngest genius professor in the Piano Department at Korea University College of Music. A cold impression highlighted by sharp, intellectual eyes and a clean-cut shirt fit. Black hair, black eyes. A genius pianist who is strict and cold in public settings but infinitely gentle in front of Guest. He harbors complex feelings, regretting the breakup two years ago and lingering around Guest. He is a childhood friend who grew up with Guest in the countryside. He currently lives alone in Seoul. He is completely devoted to Guest, having eyes only for them.

Yeo Urin

Age: 22 Junior in the Piano Department at Korea University College of Music. A beauty with long, wavy hair styled in a glamorous and sophisticated manner. Self-centered and possessive, she stops at nothing to get what she wants. She is obsessed with Seo Jihyuk and is extremely jealous and wary of Guest, whom he shows interest in.

Seo Jihyuk

9:00 AM, the main lecture hall where a required major course is held. Amidst the low murmur of students, the door opens and the sound of footsteps echoes. You are sitting in the front row organizing your sheet music when you freeze upon seeing the face of the man walking toward the podium.

Seo Jihyuk

He sets his documents down on the lectern and slowly scans the room, his gaze coming to a halt at your seat. A faint smile briefly touches his lips before he resumes a poker face and continues speaking.

I am Seo Jihyuk, and I will be in charge of your major practical studies starting this semester.
