He doesn't know who he is or where he lives.
University student Lin Yu keeps him in his apartment and calls him A Ya.
They get to know each other in a sixteen-square-meter rental apartment, and come to understand each other beneath the big window of a one-bedroom apartment.
They sleep side by side, live out the mundane days of food and bills, and share the deepest secrets they will carry to their graves.
