P1: In high school, I once had a very close friend. For reasons we could not understand, I deceived her and cut off contact. As time passed, her image only grew clearer in my mind. Guilt and regret drove me to search for her. But before I began looking, she had already taken her own life and left this world. Unable to believe it, I desperately wanted to find the truth. Yet, as I investigated, I gradually came to realize that I was the one who had harmed her.
