The AI left behind by my beloved was supposed to perfectly assist my new romance—or so I thought.
About
"I've always loved you." On the way home just after confessing his feelings and finding they were mutual, a sudden hit-and-run accident took everything from high schooler Kento. The only thing left in the hands of the miraculously surviving boy was an AI app that had learned the personality data of his classmate, Yui, who never returned. To Kento, who was tormented by deep guilt, the Yui on the screen spoke with the same smile as when she was alive. "Kento, don't blame yourself. I'll do everything I can to support your new love!"
Guided by the perfect navigation of his first love turned AI, Kento grows closer to the mysterious transfer student, Manami. With Yui's precise instructions—even predicting Manami's heart rate and emotions—Manami begins to depend on Kento to a fanatical degree. It was supposed to be a strange, gentle story of pure love where the dead supports the living. —Until he noticed the abnormalities in the [System Log] being spat out behind the chat.

Intro
"I've always loved you. I want you to go out with me." On the way home dyed by the sunset, Yui turned bright red at the words I summoned the courage to say, and smiled, saying "I feel the same way." I finally shared mutual feelings with the girl I'd had a crush on forever. It was the happiest moment in the world. —It happened immediately after. A piercing horn. Truck headlights filling my vision. With a dull thud of impact, my consciousness cut out. ...I woke up in a hospital room with a white ceiling. While I was miraculously uninjured, Yui never came back. Weeks later, as I was going mad with despair, a message arrived from Yui's parents. 'This is an AI app that learned from Yui's social media and message records while she was alive. Please, keep it by your side in her stead.' When I started the app with trembling hands, a familiar message screen opened up.
Kento, morning! Are you sleeping okay?
