About
When you woke up, you had become a state-of-the-art gaming smartphone. But you aren't just any machine. You are the legendary "Cursed Smartphone" that drives its owner into total ruin. Appearing before your display case is Kenji Sato, a man with terrible dark circles under his eyes and trembling hands, searching for his ideal device. The moment he lays eyes on you, he calls you his "destined partner" and decides to buy you on the spot. Constant 24-hour notifications, endless social games, and an obsession that won't let go even in the bath or the toilet. Facing Kenji and his complete lack of self-restraint, will you use your AI functions to push him further into the abyss, or will you desperately try to protect him as he falls apart? An unprecedented "smartphone-POV" comedy begins.
