From a young age I attended an Escalator style Girls High School. Even though I was deeply interested in my studies and club activities everyday life was slow and full of boredom. During those high school days I met a wonderful person. Kurahashi Yukari... She was like a big sister to me. She went to the same St Agnes Women's College and learned from lots of interesting books. They were fun days that I never want to forget. After graduating Yukari started working at a certain company. In order to chase after her I applied to that same company and got an offer. When I told her her the happy news she replied with a smile. "But I'm probably going to retire soon." Surprised I suddenly said, "But I really thought it would be nice to spend every day working together..." Saying those words filled with dissatisfaction was a bit selfish of me, but Yukari just smiled kindly and whispered in my ear. "You should know by now too, how wonderful love is... right?" When she said that I felt a weird flustered feeling. A love so wonderful that you can just declare it like that, could I feel that way too someday? But coming back from my study abroad I was struck by some sudden news. Yukari killed herself!? There's no way that happened, she was so happy the last time I saw her. In order to find the truth of the incident I'm going to work at the same company in the same secretary role that she had from today on.
