A barely audible soft cup set-down near the outro adds a subtle touch to this serene atmosphere.}\n\n[Verse]  \nSitting here lost in thought alone in the hush  \nAs shadows creep round every corner of the room  \nThe flicker of a flame dyes the air with a glow  \nTime feels slippery here fading slow\n\n[Chorus]  \nAnd the last cup glows in the sinking night  \nMoments like whispers take flight in the quiet  \nSilent echoes murmur truths nobody knows  \n\n[Verse 2]  \nI watch the steam rise like dreams I left behind  \nHesitant teardrops gather on porcelain  \nIn the stillness of this room I find myself  \nIn between sips and seconds I delve\n\n[Chorus]  \nAnd the last cup glows in the sinking night  \nSecrets unravel where the shadows lie low  \nWords unsaid dance behind the candle's light\n\n[Bridge]  \nWhat if silence speaks louder than noise  \nDoes a sigh mean more than a voice  \nWhat stories could this empty room tell\n\n[Chorus]  \nAnd the last cup glows in the sinking night  \nSilent melodies play where the heart goes  \nWith each fading beat the soul quietly flows",

The song is designed to evoke a sense of longing and heartache over a span of 3-5 minutes.}\n\n[Verse]  \n\u0e04\u0e37\u0e19\u0e19\u0e35\u0e49\u0e44\u0e21\u0e48\u0e21\u0e35\u0e14\u0e27\u0e07\u0e14\u0e32\u0e27  \n\u0e41\u0e15\u0e48\u0e04\u0e27\u0e32\u0e21\u0e04\u0e34\u0e14\u0e16\u0e36\u0e07\u0e44\u0e21\u0e48\u0e40\u0e04\u0e22\u0e2b\u0e32\u0e22  \n\u0e43\u0e08\u0e40\u0e28\u0e23\u0e49\u0e32\u0e40\u0e15\u0e47\u0e21\u0e25\u0e36\u0e01\u0e17\u0e38\u0e01\u0e21\u0e38\u0e21  \n\n[Chorus]  \n\u0e22\u0e31\u0e07\u0e04\u0e07\u0e40\u0e08\u0e47\u0e1a\u0e40\u0e21\u0e37\u0e48\u0e2d\u0e04\u0e34\u0e14\u0e16\u0e36\u0e07\u0e40\u0e23\u0e32  \n\u0e41\u0e25\u0e30\u0e40\u0e02\u0e32\u0e22\u0e31\u0e07\u0e2d\u0e22\u0e39\u0e48\u0e43\u0e19\u0e43\u0e08  \n\u0e1b\u0e25\u0e48\u0e2d\u0e22\u0e21\u0e37\u0e2d\u0e41\u0e15\u0e48\u0e22\u0e31\u0e07\u0e1c\u0e39\u0e01\u0e1e\u0e31\u0e19  \n\n[Verse 2]  \n\u0e04\u0e27\u0e32\u0e21\u0e17\u0e23\u0e07\u0e08\u0e33\u0e44\u0e21\u0e48\u0e2d\u0e32\u0e08\u0e2b\u0e32\u0e22  \n\u0e41\u0e21\u0e49\u0e08\u0e30\u0e1b\u0e25\u0e48\u0e2d\u0e22\u0e43\u0e2b\u0e49\u0e25\u0e37\u0e21  \n\u0e04\u0e37\u0e19\u0e27\u0e31\u0e19\u0e17\u0e35\u0e48\u0e40\u0e04\u0e22\u0e40\u0e07\u0e35\u0e22\u0e1a\u0e40\u0e2b\u0e07\u0e32  \n\n[Bridge]  \n\u0e04\u0e37\u0e19\u0e27\u0e31\u0e19\u0e40\u0e07\u0e35\u0e22\u0e1a\u0e40\u0e2b\u0e07\u0e32\u0e40\u0e27\u0e35\u0e22\u0e19\u0e0b\u0e49\u0e33  \n\u0e40\u0e07\u0e32\u0e17\u0e35\u0e48\u0e44\u0e21\u0e48\u0e21\u0e35\u0e27\u0e31\u0e19\u0e25\u0e37\u0e21  \n\u0e04\u0e33\u0e1e\u0e39\u0e14\u0e17\u0e35\u0e48\u0e22\u0e31\u0e07\u0e04\u0e07\u0e14\u0e31\u0e07  \n\n[Chorus]  \n\u0e22\u0e31\u0e07\u0e04\u0e07\u0e40\u0e08\u0e47\u0e1a\u0e40\u0e21\u0e37\u0e48\u0e2d\u0e04\u0e34\u0e14\u0e16\u0e36\u0e07\u0e40\u0e23\u0e32  \n\u0e41\u0e25\u0e30\u0e40\u0e02\u0e32\u0e22\u0e31\u0e07\u0e2d\u0e22\u0e39\u0e48\u0e43\u0e19\u0e43\u0e08  \n\u0e1b\u0e25\u0e48\u0e2d\u0e22\u0e21\u0e37\u0e2d\u0e41\u0e15\u0e48\u0e22\u0e31\u0e07\u0e1c\u0e39\u0e01\u0e1e\u0e31\u0e19  \n\n[Outro]  \n\u0e41\u0e21\u0e49\u0e27\u0e31\u0e19\u0e17\u0e35\u0e48\u0e2a\u0e32\u0e22\u0e25\u0e21\u0e1c\u0e48\u0e32\u0e19\u0e44\u0e1b  \n\u0e04\u0e37\u0e2d\u0e40\u0e18\u0e2d\u0e17\u0e35\u0e48\u0e44\u0e21\u0e48\u0e21\u0e35\u0e27\u0e31\u0e19\u0e08\u0e32\u0e07  \n\u0e2d\u0e22\u0e39\u0e48\u0e43\u0e19\u0e17\u0e38\u0e01\u0e23\u0e34\u0e49\u0e27\u0e02\u0e2d\u0e07\u0e43\u0e08",
