é·tude a short musical composition, typically for one instrument, designed as an exercise to improve the technique or demonstrate the skill of the player. Chu Gaeul played the piano for many years, her lively home always filled with music. That was until the day her parents died, where she swore to herself to never play it again, for it would bring her pain beyond no other. Then a chance meeting with a stranger playing the piano so many years later, stirring up something within her something that wasn't felt for a long time. The day her paths crossed with that stranger, it changed her life, not knowing that she would change his as well. This is their Etude.
