See With Your Heart [Lashton ; Malum]

Calum likes to joke and say that when Ashton was younger, he looked in the mirror and the reflection of him being a physical ray of sunshine is what made him go blind. In reality, Ashton had been born blind and Calum was his best friend growing up.
Luke is a born pessimist, never being able to see that grand silver lining. Not like it's particularly that grand anyway. What is one person's silver lining, is someone else's rain cloud. That's just how he sees the world. The only exception is his best friend Michael, who can somehow get Luke to see something happy once in a while.
So when Michael is out with Calum one day, Luke reluctantly tags along, and in that one turn of events he runs into the physical ray of sunshine and something just sparks.
