There’s a phenomenon known amongst the terminally ill and the elderly called the Last Good Day. For most people, it’s impossible to know when that last good day will be. You don’t know you’ve had your Last Good Day until you’re certain you’re about to die, then you look back over the last few weeks and think, ah, that was it.
Being a fortune teller, Aiura knew. She saw those next few days ahead of her and they weren’t pretty. She’d decline and decay until she died. A day with only mild pain was as good as it was going to get for her, so she wasn’t going to have any regrets. She was going to spend her last good day exactly how she wanted to.
Shopping for clothes would be pointless, though that was the kind of thing she used to enjoy before her diagnosis. So instead, she busted out of the nursing home where she’d been receiving palliative care, a last act of rebellion, and headed off to one of the best cafes in the little town where she lived. After an indulgent breakfast, she took the train into the next biggest city and went to the movie theater where she spent the day watching three new releases with lots of buttery popcorn. Two of the three were kind of crappy, but she enjoyed them anyway. Before the sun completely faded behind the horizon, she rode the train back to her town.
She walked down the road, beginning to feel the consequences of spending the whole day outside and away from her cushy bed. Her back was stiff, her breath was coming more deeply and slowly, and her head pulsed. But it wasn’t too bad, so she decided to make one more stop before returning to the nursing home to get scolded by her nurses for leaving without telling anyone.
The corner convenience store sign blinked an inviting red. She entered and made her way to the aisle full of snack cakes. Scanning the different varieties, her eyes eventually landed on the last box of her favorite chocolate cakes. As she reached for them, her hand, not as pristinely manicured as she’d prefer, bumped into pale fingers.
Looking up, her gaze climbing that slender arm until it reached the face attached to it, she realized this was someone she knew. Saiki Kusuo, her old classmate from high school, and her soulmate. He never seemed to agree about that last part, though. No matter, she was excited to see him. She hadn’t predicted this happening, but when it came to Saiki Kusuo, her predictions often missed the mark.
Instinctually, she offered the last box of chocolate cakes to him. And maybe that was the beginning of the chain of events that culminated in Saiki kissing her in the doorway of his apartment that night, him committing to restore her health everyday until that Last Good Day blossomed into an entire lifetime, and him finally falling in love with her.
