是我犯贱把赔笑当溺爱
[shì wŏ fàn jiàn bă péi xiào dāng nì ài]
Saying 'It's my fault for mistaking a forced smile as doting love', indicates feelings of regret over misinterpreting another’s fake kindness or forced smiles as genuine adoration or affection. Often reflects post-breakup reflections on what was misunderstood in a relationship.
