Seeing how perceptive Aki is of Tama, whether it be her condition, her feelings, everything around her, it's honestly so very sweet to witness. He kind of reminds me of Toushirou from Bleach who's so protective of his own childhood friend (to the point where he'd kill if someone made her shed a single drop of blood... yeah they're definitely the same species owo;;
But it makes me want to root him so much more ;w;
