他城地牢锁她她心城堡守他
[tā chéng dì láo suŏ tā tā xīn chéng băo shŏu tā]
In his city's dungeon she is confined, in her heart a castle stands guard over him. This complex phrase uses metaphors about being imprisoned in dungeons in distant cities contrasted against protecting someone within your own fortress of feelings/heart. This creates vivid contrasting scenes and emotional depth regarding complicated and unreciprocated or forbidden romance between two individuals bound by fate.
