Some things I've noticed: The idol Akane actually shows up briefly in chapter 4 in a photo with Mei. It seems as though Akane is also friends with Rinna, and in chapter 5.2 we're briefly shown a flashback with Rinna in what appears to be an idol outfit collapsed on the ground. In the brief flashback we're shown Mei who appears to be worrying over the collapsed Rinna.
So here's my theory: Rinna and Akane were idols together. Whether they were a duo or part of a group, I can't say. Anyway, something happened to cause Rinna collapse and a nearby Mei rushed over to help. As a sort of thanks, Akane did a photo op with Mei. The incident also caused Rinna to fall in love with Mei, but for whatever reason Mei forgot about her.
Of course, that's just a theory, and I'll admit that it's not perfect.
