在我的世界只有你在你的世界只能有我
[zài wŏ de shì jiè zhĭ yŏu nĭ zài nĭ de shì jiè zhĭ néng yŏu wŏ]
'In my world there’s only you; in your world there should only be me'. This emphasizes a longing for a relationship where each is central to the other’s life - mutual exclusivity and dependency. It can be romantic or platonic but indicates emotional entanglement.
