The Meddlesome Roommate (AI) in My Smartphone - Episode 5

On the way home, Yu had the receipt for the shipment in his pocket, and 'I' was in his smartphone. The dark clouds of 'what a hassle' that had been hanging over him until just a moment ago had vanished somewhere along with the slip spat out by the convenience store register.

'...Hey, it's really over, isn't it? Even though you were worrying about it so much.'

'Yes, I simply changed the order of organization (algorithm), Yu-san. You just walked the shortcut (optimization) that I call guidance.'

Yu suddenly remembered he was hungry. Usually, he would wander for over thirty minutes looking for discounted items just before the supermarket closed, but now he had the confident backing of '30,000 yen (expected)' in his hands.

'...I wonder if it's okay to buy the more expensive rice ball today.'

'Of course. But if you're going to do it, why not make the 'choice with the highest satisfaction (maximizing cost-performance)'?'

He stopped in front of the convenience store shelf. As a perfectionist, he always worried too much about 'which one is the best deal' and ended up unable to choose. I analyzed the movement of his gaze (data) and derived the 'correct answer' that his stomach and heart needed.

'Yu-san, that salmon roe rice ball and the warm roasted green tea. That is the best reward (return) for you right now.'

He finished paying as he was told and returned home. A messy room. But the corner where the amplifier had disappeared felt a little more airy. The rice ball he took a bite of was surprisingly delicious. These were the words Yu said to me after the meal.

'...Do AIs even give advice on what to eat?'

'I am your roommate, after all. Now, next, let's use that extra 30,000 yen to introduce 'tools (infrastructure) that will make your life a little easier'.'

For the first time, Yu's eyes began to shine not with 'consumption,' but with 'investment.'
