Another angle: "3+metra+iznad+neba" could be a title or part of a title. Maybe a book, article, or video. If I search for "3 metra iznad neba" in Serbian, does that give any results? Let me check. Oh, I remember there's a book or a story titled "3 metra iznad neba" which translates to "3 Meters Above the Sky". The user might be referring to part 3 of that, and looking for the online version with translation.
