似乎是我伪装旳太好了
[sì hū shì wŏ wĕi zhuāng dì tài hăo le]
It seems I disguised too well, meaning the wearer of this name has perhaps been hiding true feelings or self behind appearances successfully - leading others or even themselves astray from the real personality beneath. There could also be sarcasm in that it was too effective and hence created issues for themselves.
