Imagine inviting all of your exes over at once to pick up their stuff. How could this go well?
This feels like a power play by Touko with multiple effects. Touko gets to bring Akari closer to her by showing how in demand she is and spark some jealous possessiveness in Akari. She also wants to flex and spark envy and desire from the exes by showing she can seduce a high school girl and show how many beautiful women she has been with. That seems to have worked on Ayano, who reacted to Akari by trying to talk her into moving out of all things.
Touko is coming off as a master manipulator. But don't hate the playa, hate the game!
