Layered guitars and pads create a rich, atmospheric background; Structure: Intro - Verse - Chorus - Verse 2 - Bridge - Chorus - Outro; Language: Mandarin; Highlight: The strained, emotional high-note delivery on the word \"爱\" (ài) in the chorus", "lyrics": "[intro]\n(Chords: F#m - D - A - E)\n(Inst: Clean electric guitar plays a repetitive, melancholic arpeggio with heavy reverb and delay. A low, atmospheric synth pad swells underneath.
