How to understand 君だけ in this sentence?

Question

I hear the sentence from the song『星のかがやきよ ZARD』

君だけは変わらないでいて欲しい

I think there are 2 ways to interpret it:

1. I only want you to remain unchanged. (The person whom I want to remain unchanged is only you.)
   
2. I want that only you remain unchanged. (I want that the person who remain unchanged is only you).
   

There is slight difference between them. In 1, "only" is associated with "want", which indicates: maybe other people will change, but I don't care.
However, in 2, "only" is associated with to "remain unchanged", which indicates: I want you remain unchanged and I want others to change.

That's to say, whether だけ in the sentence is associated with 欲しい or 変わらない will lead to different interpretations.

Considering the context, I think the first interpretion is correct. But does the second also make sence if we only consider the meaning of the single sentence?

Answer 1

This can't be #2. The sentence isn't constructed correctly for that. #2 would have to be rendered along the lines of (if sticking with the current word choice)

変わらない君がほしい

And it seems to me that 君がほしい sounds overly sexual.

ほしい expresses a desire, not a wish. If you would want to express a wish you need to use ねがいor のぞみ. Neither of those ideas are in the provided sentence.

I'm not sure about your sentence #1. The subject of the sentence is "I". We know that because of the form of ほしい. The structure of てほしい expresses the speaker's desire that someone do something for them.

So, I would suggest rendering this sentence as

I want you alone to [remain] unchanged.

"remain" here is my attempt to capture what's happening with 変わらないでいる. But no where in this sentence is the idea of "never" expressed (though certainly suggested).
