你爱得深了你认真你就输了
[nĭ ài dé shēn le nĭ rèn zhēn nĭ jiù shū le]
This phrase means 'When you love deeply and take it seriously, you lose.' It implies that when one falls deeply in love with someone and gives too much thought or effort into the relationship, there will likely be emotional setbacks. It reflects some cynicism about the consequences of taking things like love too earnestly.
