Right now Isabelle doesn't understand what Cetafe means. She still feels that it is better to have the opportunity to choose. She is a human being, shouldn't people make one decision after another throughout their lives? Why do you have to follow other people's arrangements... It looks silly and has no logic at all. Thinking of this, Isabelle felt like she was still a very normal existence, so she didn't even understand why she was outside this door. She stood here like a silver-haired stone lion, motionless. budged a bit, but essentially, she felt that she was more willing to stay in this place because of her curiosity towards this matter.
