有你有我没你没我
[yŏu nĭ yŏu wŏ méi nĭ méi wŏ]
In this name, the meaning can vary according to different situations and emotions, generally speaking: when you're here, there's me (I exist for/with you), when you're not, it's as if I do not exist too - reflecting dependency on each other, possibly in a romantic context but could also mean anything deeper relationship, including deep friendship.
