This song is about a girl he messed things up with and he misses her.
"The solar flares burned my arms" the solar flares he referring to are the problems in their relationship, and he made her cry because the lyrics say "and made her makeup run".
He still remembers everything about her, so he used metaphors throughout the song to portray everything she liked and everything about this special girl.
I hope you found this helpful, it's just my opinion :)
