What is the subject of this sentence?


I'm translating a song which can be seen
[here](http://www.youtube.com/watch?v=SUQV5g9QoUA). At the end of the song is
this:

> 傷つけてしまう夜もあるだろう 分かち合えない想いもあるだろう

What is the subject of 傷つけてしまう夜もあるだろう? Is the singer saying, "there may be
nights where we'll end up hurting each other," or is he saying, "there may be
nights where I'll end up hurting you?"




After reviewing the song, I've completely flipped on my answer. The whole song
is definitely from his perspective, and this part is definitely him saying he
might hurt her feelings.

Original Answer:

I definitely feel it's the 'each other' one. It's just saying that there are
days they will hurt each other's feelings, and days they won't think the same
way. I expect the rest of the song talks about how good they usually are
together, or how much they love each other and it's okay, etc.




It seems to be the former. If it were "each other", it would need to be an 〜合う
verb (like the latter), like 傷つけ合う夜 (or with しまう, 傷つけ合ってしまう).
