面具背后殇
[miàn jù bèi hòu shāng]
"Mask behind, sorrow follows." This net name might indicate inner pain, secrets or sadness which are hidden by outer behavior or appearance - wearing 'a mask' often signifies putting on a facade that doesn't display the real emotions of an individual. In this case, despite outward displays, there might have been hurtful memories, situations causing distress or struggles within the person.
