深爱无怨付出换来全是伤
[shēn ài wú yuàn fù chū huàn lái quán shì shāng]
'Unconditional Love Only Resulted in Wounds'. This indicates someone who is disillusioned by the result of loving too much, perhaps from experiences of deep but ultimately harmful one-sided or unrequited love, where they have put in everything emotionally yet were severely hurt or failed in getting anything back.
