谁说我非要爱你不可啊撒比
[shéi shuō wŏ fēi yào ài nĭ bù kĕ a sā bĭ]
It can be understood as asking rhetorically, 'Who says I must love you anyway, idiot?'. Here 'ah sa bi' seems like a casual interjection used for expressing frustration or anger. It reflects a defiant and slightly sarcastic mood against the conventional thought.
