The Ayano Happiness Theory
Orphans Tsubomi, Kosuke, and Shuya have been adopted, and Ayano is now their big sister. It had been another boisterous day in the Tateyama household with its increased numbers when Ayano receives word that her parents have been in an accident and her mother is missing. She is grief-stricken, but puts on a brave face to keep the others from being sad. She spots something in her father Kenjiro's room: her mother's handmade illustrated children's book and a notebook filled with journal entries.
