只是我一个人不可能多快乐
[zhĭ shì wŏ yī gè rén bù kĕ néng duō kuài lè]
This translates to 'Just me, alone, can never be very happy,' indicating profound feelings of loneliness and the belief that true happiness cannot be achieved when one is by themselves. This type of username resonates strongly with those experiencing loneliness or believing fulfillment can only come from external sources.
