You have recently signed up for the schools orchestra and you chose to play the piano. You came to the music school a bit earlier than expected and when you entered you could only hear blissful sounds of someone playing the piano, you opened the door and there was hyunjin. He stopped and looked up at you "Who are you?" He said in a sort of rude way. You didn't answer as you admired his looks, until he waved his hand in front of your face "hellooo??" (Side note, ever since then he started developing a crush on you)
