It should be:
小酒窝长睫毛 迷人得无可救药
我放慢了步调 感觉像是喝醉了
终于找到心有灵犀的美好
无可救药:incurable
Here, it means, the girl has 小酒窝,长睫毛,which are so attractive to the boy. The boy seems to be addicted to her beauty. This kind of addiction is incurable.
Another example could be:
Sam is very very lazy. His mom told him to study hard but he can't do that. Her mom might say: 你真是无可救药了!
心有灵犀:
For example: When you are considering to call me, you receive my call. You could say:" 我正想打给你呢,我们真是心有灵犀啊!”
It means we know what each other's thinking about.
