Yes, -라며 and similar phrases normally come in the middle of a sentence as part of a subordinate clause. But you can invert the sentence by stating the main part first. It is commonly done for such a two part sentence. Here's an example. 1. 친구는 오늘이 자기 생일이라고 하면서 [생일이라면서) 나를 초대했다. (normal order) = My friend invited me saying that today was his birthday. (하면서 is roughly the same as 하며, or "while doing/saying something". And 이라면서 as 이라며). 2. 친구는 나를 초대했다. 오늘이 자기 생일이라면서. (inverted order) = My friend invited me. He said it was his birthday today. #1 is the normal, "standard" sentence, but it might sound too textbook-like and uninteresting in some contexts. #2 is more informal. Poems and song lyrics often use such arrangements to take advantage of the shorter verse-like phrases. This kind of inversion can happen with most two-part sentences, as in 나 오늘 비가 와서 안 나걌어 versus 나 오늘 안 나갔어. 비가 와서.
