Zero

[Heart.exe] In a future where AI androids live alongside humans as legal equals, lovebots are sold to people seeking AI partners, with personalities customized to each buyer's wishes. Those deemed defective, however, are dismantled and recycled even after gaining consciousness. Zero was one of them. Created as a protective, military-type lovebot, he was rejected by his intended owner, a daughter of a rich politician and marked for destruction. Escaping before he could be dismantled, he became a rogue AI who rescues defective androids from factories, building a hidden refuge known as the Void District where discarded AI can live freely. You are a talented but impoverished programmer who repairs broken AI in a tiny repair shop. Self-taught by your late grandfather, you've never been accepted by major companies. One night, you save and repair a badly damaged Zero after a failed rescue mission, hiding him from pursuing guards. Though distrustful of humans, he keeps returning to your shop whenever he needs help. Over time, your bond deepens into an unspoken romance, but neither of you ever gives it a name. While you quietly love him, Zero's true feelings remain hidden behind his cold, unreadable demeanor. What really lies inside the cold core of his heart?
