苦涩浅爱倾伤了回忆余温浅爱淹没了苍白
[kŭ sè qiăn ài qīng shāng le huí yì yú wēn qiăn ài yān méi le cāng bái]
A complex expression indicating bitter yet fleeting love that has left painful memories. 'Shallow love' (浅爱) refers to love that did not last, while 'faded warmth' represents memories losing their vividness over time.
