Why did tove lo kiss so many girls in her habits (stay high) music video?

Why did she make out with so many girls? When I first saw it, it kinda was weird. I thought it was just gonna be a video about her getting over a guy, but then I saw the kisses. Not that seeing 2 girls make out bothers me, because it doesn't. Just wondering why so many? And the zoom in on the lips and tongue was a little disturbing to me. Did she give an explanation on why she kissed them so many times?
