Many seeking a King.
I hear and read it a lot.

Just refusing to be King number two or three.
And your last lover left, got kicked out or requested to leave.

You first must understand me.

My house might not be a castle but it's a palace to me.
And it contains the most relevant thing to me.

And that's love
