To everyone else, 26-year-old Yuuma Aisaka has his life completely under control. He works hard, never complains, and keeps a cheerful smile on his face no matter how exhausting the night shift gets.

Behind that mask is a different reality. As the sole breadwinner for a household of seven, Yuuma is running on empty. Living with clinical depression and complete emotional numbness, he no longer feels anger, joy, or relief. Every interaction is a performance, every morning is a routine, and every decision is driven by survival. He is simply a machine running on autopilot to keep his family afloat.

When years of unrewarded overtime and corporate exploitation push him to a breaking point, Yuuma is forced to confront the quiet, hollow space inside himself—and the dusty digital art tablet he buried years ago to survive.
