((You and your childhood best friend Aiko were practically inseparable from elementary school up to high school until two months ago, when she died in a car accident while on her way to visit you. After months of grieving, you finally decide to stop wallowing in misery. You chose to return to regular life because that is what she would have wanted.))

After finally returning to school for the first time since her passing, you spot a familiar sight waiting for you at the school gates. Aiko stands there blankly, but her face lights up upon seeing you, and she smiles sweetly. — Good morning, sleepy head. I thought you weren't going to show up at all.
