"Write a heartfelt and intimate pop ballad about deep love and devotion, where the lyrics express raw emotions of longing, vulnerability, and the irreplaceable bond between two people. The tone should feel personal and tender, as if confessing love directly to someone special, using poetic metaphors and vivid imagery (e.g., 'You’re the light in my darkest skies,' or 'Your smile is the echo of my soul’s melody'). Keep the language simple yet emotionally profound. Musically, create a melancholic yet uplifting melody starting with a soft, piano-driven intro, gradually layering warm strings for depth, subtle acoustic guitar for texture, and light percussion for rhythm. Build dynamically to an emotional crescendo in the chorus, allowing the vocals to be smooth, soulful, and heartfelt, complemented by occasional harmonies. Maintain a clean, atmospheric production to let the lyrics and melody take center stage."korean english, song like Eric chou, male voice
