Translating the three lines literally
The sun beyond your ears
is so beautiful
feels like my breath (out) would disappear (I might be misunderstanding or mistranslating this part. I don't know how else I would translate 息をかける)
Further down, she says
Which makes think the season is summer. Further down, she also talks about Beach Boys playing on the radio. Which further strengthens the summer feeling.
If the season is summer, first three lines (third line especially) sound confusing
The setting sun beyond your ears is beautiful.
Sun beyond the ears strikes me as an odd way of putting it somehow. I wonder if it actually means something else and how does it tie up with first two lines before?
And then the third line says
Why does she say "as if my breath would disappear" here if the season is summer?
