你爱我注定只是一场梦
[nĭ ài wŏ zhù dìng zhĭ shì yī chăng mèng]
The phrase 'Ni Ai Wo Zhu Ding Zhi Shi Yi Chang Meng' ('你爱我注定只是一场梦') means 'It was destined that your love for me is just a dream'. This conveys a romantic or sorrowful mood, where the person believes the love they receive is not real but merely an illusion.
