爱可以跟很多人说但是我只想跟你说
[ài kĕ yĭ gēn hĕn duō rén shuō dàn shì wŏ zhĭ xiăng gēn nĭ shuō]
'Ai Ke Yi Gen Hen Duo Ren Shuo Dan Shi Wo Zhi Xiang Gen Ni Shuo' translates roughly to 'love can be spoken about to many but I only want to tell you.' It's an expression of a very special feeling exclusively reserved for one person, expressing dedication or uniqueness.
