天空依旧深蓝但又不蓝阴天下雨了雨陪我哭泣
[tiān kōng yī jiù shēn lán dàn yòu bù lán yīn tiān xià yŭ le yŭ péi wŏ kū qì]
This long and poetic username roughly translates to 'The sky remains deep blue, but it's not blue on an overcast day; it's raining which accompanies my crying'. It expresses a melancholy mood, associating one's inner sadness with the weather conditions outside, reflecting the harmony between emotions and nature.
