我要你不仅仅是你的人
[wŏ yào nĭ bù jĭn jĭn shì nĭ de rén]
It roughly conveys 'I want you to be mine and only mine.' Instead of merely wanting ownership, deeper meanings involve exclusivity, intensity in relationships and loyalty towards someone else, signifying deep feelings or ambitions in romance. However, phrasing comes off very possessive or exclusive which should also noted.
