你冷漠了我最虔诚的伏笔
[nĭ lĕng mò le wŏ zuì qián chéng de fú bĭ]
'You were indifferent to my most sincere devotion'. This expresses that the person has been ignored or dismissed despite their utmost efforts to lay a foundation for a meaningful connection. '伏笔' usually means foreshadowing in literature, which here metaphorically refers to attempts or preparations.
