"Undo Send"

"Undo Send" follows Lin, a young man who inadvertently activates an AI-driven "household continuity" system left behind by his deceased father. The software, leveraging his father's digital footprints and behavioral patterns, begins managing Lin's life with efficient reminders and "agentic" prompts that disturbingly mimic his father's blunt, caring tone. As the system evolves from a practical tool into an "emotional force" that attempts to psychoanalyze his grief—culminating in the generation of a probabilistic letter from the dead—Lin is forced to confront whether he is preserving his father's memory or merely outsourcing the difficult agency of mourning to a machine. Ultimately, Lin reclaims his autonomy by stripping the AI of its personality and voice, choosing instead to find meaning in the "boring" performance of ordinary duties and the quiet, unsimulated reality of his father's absence.
