The search for a full set of limited edition rainbow coloured makeup brings two unlikely girls together. Amber runs a semi-popular makeup channel. It combines the two things she loves best, makeup and teaching people. While talking face-to-face with people scares her, talking to a camera is much easier, it feels safer. That distance between herself and the people who watch her videos has always been right for her, until she meets a girl who makes her rethink everything she does. Mya is a girl of many interests, from gaming to anime and manga to makeup and clothes, she loves it all. What she likes even more is to share her passions with other people, and she surrounds herself with those who love similar things. She's good at talking to people, she loves it even, but then she meets one girl who could undo all of that and expose her much darker side... A new makeup brand brings out a rainbow themed collection and as both girls work together to collect every last piece of it, their lives start to change in ways they never expected.
