Their fingers entwine over the keys. Kang Bi-oh: "I'm not dragging, it's a syncopation. Don't you know how to read music?" Choi Jeong-yo: "Ha, talking back now?" Though they growl at each other as if to devour one another, their hands create a perfect harmony as if by promise. It was a terrible contradiction.
