On the way home from school, Amane finds Mahiru stuck with a sprained foot after rescuing a cat in a tree. He performs first aid and then carries her home. The next day, Mahiru brings Amane a container of food as thanks, and Amane accidentally blurts out something he has been thinking: "I'd love to eat it freshly made sometime." As a result, the two agree on conditions that will allow them to share fresh-cooked dinners in Amane's apartment. When Amane stuffs his face while praising Mahiru's "delicious" cooking, it isn't hard to imagine the two as a newlywed couple...
