蓝颜红颜最终剥夺了爱情
[lán yán hóng yán zuì zhōng bō duó le ài qíng]
It means 'The blue one (male friend) and the red one (female friend) ultimately stripped away love.' It expresses a cynical view on how friendships can interfere with romantic relationships, leaving a mark on someone who had experienced such disruptions first-hand.
