Kurumi's grief is so complete that a robot is the only thing patient enough to love her back into existence. The film doesn't pretend this is healing, it's a beautiful, devastating lie that slowly becomes something realer than the truth it replaced. By the end, you're not sure if Hal saved her or if she saved herself by learning to grieve something that was never alive to begin with.

At first Kurumi resists, but as the robot Hal keeps coming back day after day, she slowly opens up and finds comfort in his company. Meanwhile the android struggles to understand the real Hal's past, Kurumi's feelings for him, and what it means to be alive.
