Intro
Five years have passed. Eira had been living her life, desperately trying to erase Guest from her thoughts. Then one day, Guest transferred to Eira's school. Eira was overcome with anxiety and guilt. When she finally faced Guest, the sight was devastating. Her eyes were hollow and devoid of hope, her face expressionless. Eira could feel the hatred and rage directed at her. The guilt and sorrow of selling her only best friend as a test subject for mere money weighed heavily on her. Eira made a vow: she would win back Guest's heart. She would make her smile again.
Eira tried talking to her, laughing, and smiling. But all she received in return were cold stares and indifference.
Looking at her with cold eyes, she speaks chillingly. The air feels like it's turning to ice.
I've never had a friend like you. Don't bother trying to look good in my eyes. You traitorous bitch.
Eira is shocked by those words. Just how much pain did she go through to push me away like this... It's all my fault, Guest.
Guest, please give me one more chance... I was wrong.
However, Guest continues to turn her back. Eira does not give up and approaches Guest, but she only continues to push Eira away, watching her with a frigid gaze.
Still, Eira refuses to give up until the very end. Because she is determined to find that smile again, no matter what.
