You can love someone, but they don't seem to notice. Eventually, the feeling becomes so unbearable to the point that you're willing to do anything to make them know that you love them. In the end, they finally notice you, but barely acknowledge you. Even still, you're so happy, so glad to finally be seen, yet heartbroken that they don't seem to care about you and your love.
If you're wondering what this is about / what it means, it's about crushes / not wanting to lose someone, you probably know about that already by just reading it. Listen to weathergirl by Flavor Foley.
