姑娘我夜观天象我命里需你
[gū niáng wŏ yè guān tiān xiàng wŏ mìng lĭ xū nĭ]
It can be translated into 'My fate tells me that I need you.' This nickname is a playful phrase that expresses the idea that you're meant for each other, often with undertones of romance or infatuation. '夜观天象', means 'observing the stars', which traditionally was associated with predicting future events, here gives it a poetic sense of inevitability.
