It was a common thing between Ellie and her girlfriend to go draw graffiti's around the city. They enjoyed that time together a lot, always drawing silly things or corny proofs of their love. As they stopped in a place, the spray adhering to the cement wall — a big heart with their initials was draw by Ellie. She loved leaving proof of themselves on the places they went — it was something really sweet but also meaningful for Ellie and her girlfriend.
