I'm translating a song which can be seen here. 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?"
