>>33730405From what I've read, she was angry because Lusamine only evolved Clefairy because she thought Clefable was cuter, not for Clefairy's own good. Which seems pretty stupid, it's not like evolving hurts the Pokemon and why is it any worse to evolve a mon cause you think it will look nicer than to make it stronger?
And she was annoyed at Lusamine hugging her because she thought it was embarrassing.
