The fact that Miya doesn't even ask for an explanation of any sort really activates my almonds. She doesn't know anything, continues to not try to empathize with anyone or understand anything, and just judges by herself. She didn't listen to her father when he tried to explain, she doesn't give Koto a chance to explain, it's really all about her and her own feelings for her. And then she's all magnanimous with the big friendship declaration, when she's actually still as selfish as she's been all along.
