Perfect.Murder contacted Gui to ask about his design. Here's his response:
"The idea comes from distilling the song into two icons: Friday and Love, hence the colour red. I wanted to build a sleeve that felt as delicate as a heart ( Love, much like a Friday, often starts and ends before we can really enjoy it all the way. So the idea is a sleeve that can break, crack, scratch, depending on what you do with it. I hope that makes sense. :)"
