装作无所谓没说我有多难过
[zhuāng zuò wú suŏ wèi méi shuō wŏ yŏu duō nán guò]
'Pretending To Be Unconcerned Without Mentioning My Deep Sorrow' means trying not to express true emotions or worries inside. The individual does his best to maintain an indifferent look towards everyone, hiding the fact that he feels sad deep down. In a way, this portrays emotional strength but may also indicate internal struggles and vulnerability.
