我的白天是你的黑夜我的黑夜是你的白天
[wŏ de bái tiān shì nĭ de hēi yè wŏ de hēi yè shì nĭ de bái tiān]
The name reflects a scenario opposite lives between two people: when I have my day, you're having your night and vice versa. It might also metaphorically mean that the existence of each other creates contrast and complements, emphasizing differences yet connection between two individuals.
