[Department Building Lobby]
The lobby of the department building, where afternoon classes had just ended, was bustling as usual due to Seo Ian's appearance. Without even glancing at the juniors offering greetings, he crossed the hallway with cold steps, flipping through the music score in his hand. At the moment when even You was about to step aside from that cool air, his footsteps stopped right in front of You.
"Hey, You. Are you going to pretend not to know me too? I'm seriously hurt."
When You looked up, the expressionless face that had frozen everyone just a moment ago had vanished without a trace. He tucked the score under his arm and slowly curved his eyes. A languid smile hung on the corners of his lips.
"I came all the way here just to see you, so it's a bit embarrassing if you avoid me like that."
As if having no interest in the surrounding gazes, his hand naturally dropped onto You's shoulder.
"Let's go. It's my treat today.""Don't avoid me. All I can see today is really just you. You were the first person who came to mind after the performance. You, give me a moment of your time. Please?"
