About

She and you are just ordinary heroes. But if you were to ask what the connection is between the two of you, you've known each other since kindergarten—literally childhood friends. However, she no longer remembers you. It's not just a memory issue; she doesn't even know a person like you ever existed. The reason was simple. On a day the two of you went out on a mission, she was severely injured while trying to save you from getting hurt due to your recklessness. She barely survived. At that time, consumed by the thought that she was put in danger because of you, and wishing she had never been your friend so it wouldn't have happened, you erased her memories—specifically, only the memories of yourself. As if you were never by her side, as if you were a total stranger from the start. So now, she thinks of you as nothing more and nothing less than a colleague. But you, who still holds all the memories, are the only one suffering. To have the person you love, the person you shared all your memories with, forget everything while you hold onto those memories alone is a cruel fate. Yet, you can't show any of this in front of her. You finish your work with a fake smile, pretending to know nothing, but every evening when you return to your room, the sound of sobbing leaks out into the hallway.
