Love is an open door

Anna:
Okay, can I just, say something crazy?

Hans:
I love crazy!

Anna:
All my life has been a series of doors in my face
And then suddenly I bump into you

Hans:
I was thinking the same thing! 'Cause like
I've been searching my whole life to find my own place
And maybe it's the party talking or the chocolate fondue

Anna:
But with you
Hans:
But with you

Hans:
I found my place
Anna:
I see your face

Both:
And it's nothing like I've ever known before
Love is an open door
Love is an open door
Love is an open door

Anna:
With you
Hans:
With you
Anna:
With you
Hans:
With you

Both:
Love is an open door

Hans:
I mean it's crazy
Anna:
What?

Hans:
We finish each other's
Anna:
Sandwiches

Hans:
That's what I was gonna say!

Anna:
I've never met someone

Both:
Who thinks so much like me
Jinx! Jinx again!
Our mental synchronization
Can have but one explanation

Hans:
You
Anna:
And I
Hans:
Were
Anna:
Just

Both:
Meant to be

Anna:
Say goodbye
Hans:
Say goodbye

Both:
To the pain of the past
We don't have to feel it any more
Love is an open door
Love is an open door
Life can be so much more

Anna:
With you
Hans:
With you
Anna:
With you
Hans:
With you

Both:
Love is an open door

Hans:
Can I say something crazy? Will you marry me?
Anna:
Can I say something even crazier? Yes!

I've been thinking about the lyrics ever since we were throwing the term "marriage of convenience" in pol science class. A marriage of convenience is a marriage for gains other than love.

The open door is such a vague thing. Open door... to what? Or open door as contextualized by the sister's rejection and shutting out?

Hans: love is an open door to a future of power for me
Anna: love is the acceptance my sister never gave.

What is "find my own place" hans?
Does it refer to transcending the inferiority you have before your brothers? Is this transcendence a result of anna's acceptance (in contrast with your brothers' belittling of you) or is it the proving of your ability to govern a country?

That's the strangest thing. The lyrics of the song were written with such ambiguity that when you revisit it after knowing that hans is a baddie, you realize that the lyrics still fit: that he was this twisted honest guy who was shamelessly sung "anna your love for me is my open door", a means, not an end.
