Weeks passed. Sumire experimented with better in all sorts of small ways. She tried being better at saying what she thought without an apology. She practiced being better at leaving messages that were neither too short nor awkwardly long. She tried being better at resting. Once, on a bus that smelled of boiled cabbage and perfume, she took out her paint-splattered notebook and wrote a letter to a future self: "If you are reading this, it means you kept trying." She folded the letter and placed it in the book as if sealing a jar of something fragile.
