Haruka-chan... Haruka... Ka-chan... I wanted to protect you. But... because of the senior I hated so much, I couldn't protect you. I'm sorry. Haruka-chan, my childhood friend who was pure, serious, and smart from old times, was a goddess to me. One day, Haruka-chan was tormented by the senior I hated so much through sex... I was angry that I couldn't do anything. Haruka-chan's body was gradually corrupted, trained, and fell by the senior I hated so much... I wanted to die.
