我只做你玍命里旳唯一
[wŏ zhĭ zuò nĭ gă mìng lĭ dì wéi yī]
This unusual character '玍'(note: This might not be commonly known), if meant to mean 'lifetime' (possibly intended for '一生') would translate as 'I Only Want To Be The Only One In Your Lifetime'. Conveys exclusivity and permanence in a relationship, emphasizing a desire for lifelong partnership.
