我姓刘藏着说不出的内疚
[wŏ xìng liú zàng zhe shuō bù chū de nèi jiù]
'My family name is Liu (or I am Liu), harboring unexpressed remorse'. This signifies carrying hidden guilt within oneself, possibly from past events or experiences not ready to share. It points towards inner struggles over admitting mistakes or faults.
