谁爱的太过自由谁让爱变得沉重
[shéi ài de tài guò zì yóu shéi ràng ài biàn dé chén zhòng]
This translates roughly to 'Who loves too freely, makes love become heavy'. Love here represents emotional entanglement that turns into burden rather than being pure-hearted. It explores two people in a relationship, their differing styles or depths of loving affecting the nature of the affection between them.
