In a small town, two souls, bound by a shared sorrow, find solace in each other. She's a kind girl battling thyroid cancer, always carrying an oxygen cylinder, her life fragile and fleeting. He's a troubled musician, haunted by his past, who believes love is just an illusion. Their worlds collide when he sees her at a hospital where she spends most of her time, and despite their stark differences, they find themselves drawn to each other. As their bond grows, he begins to see her as the muse for his music, but her illness steals away precious moments, leaving him to face the overwhelming truth of how fleeting love can be. With each passing day, the girl grows weaker, and they must learn to embrace the beauty of fleeting moments before the inevitable arrives. Their journey is a melody of sorrow, love, and loss, and in the end, it's not the music that echoes but the quiet absence of the one they lost.
