We all know Zayn was the artist of the band, and that included graffiti art as well. He spray-painted a lot.
He spray-painted the walls in his houses, he spray-panted a dog statue for charity, he spray-paints in his music videos etc.
So above we see Harry watching him spray-paint quietly from behind. But we also know Harry began dabbling in spray-painting behind Zayn. The most notable instance was the pink heart spray-painted on the metal box near Zayn’s house.
Also, this is an image that Zarry spray-painted together.
Their relationship can’t be anymore involved or adorable. The way they just became each other. Sigh 🙁
