I struggle a lot to understand this sentence :

願い叶うのならひと目で **いいから**

I can't find any coherence with the first part of the sentence.

question
meaning
What is the meaning of いいから in this sentence?
> 願い叶うのならひと目でいいから  
>  If someone makes my wish come true, only a single glance will do, so
> (please let me see you!)

  * ひと目 is "glance" or "seeing for a very short time" rather than "first sight".
  * ～でいい is a construction to express your minimal desire. "(something) is not ideal but acceptable" or "～ will at least do". See: [What is the difference between それでいい and それがいい here?](https://japanese.stackexchange.com/q/17851/5010)
  * から is a reason marker. I translated it as "so" here. から is usually followed by a result/conclusion part, but it's omitted in this case. Although her wish is not directly mentioned, it is self-evident if we have access to the [full lyrics](https://genius.com/Taeyeon-voice-lyrics). She wants to see the person she loves, and that's her 願い ("wish") here.
