Amid the bustle of a thriving city, love began to play like a melody that came out of nowhere. This is the story of the male and female leads' romantic, twist-filled love.
A wrong turn in a karaoke room led the heroine to open the door that would change her fate. The hero's piano music flowed into her heart like a clear spring. Brought together by music, they hit it off, and soon began going on frequent dates as their feelings quickly grew.
However, the pressures of life and their busy work schedules challenged their relationship. Frequent arguments and silent treatment brought them to an impasse. Just as they thought their love was about to fall apart, a note that held memories of their first meeting rekindled the hero's love. He took the initiative to win her back, and after clearing up their misunderstanding, they made up.
From then on, they understood and supported each other. Their careers steadily flourished, and their love grew ever stronger. At last, in the karaoke room filled with memories, the hero proposed with a piano piece composed just for her, giving their love, which began with music, the happiest possible ending.
