And so, Jieun and I began our training. I hadn't expected her to ask me to train together, but honestly, if I could help her, that would make both of us stronger—so much stronger. After all, Jieun was a genius. I had a strange feeling that, with enough time and effort, she could easily pass me. It almost seemed impossible to believe she was only nine years old. If someone were to ask me, I'd say she was at least older than me and all of the others in the group. But I guess kids these days just grow up smarter. I, myself, was still playing with dolls at her age. Yet here she was, already one of the most powerful beings in this world.
