"Decided?"
"It's decided... Wait, I have a few more questions. Will my face look better?"
"Yes."
"Won't this affect other people's memories? In other words, in their impression, my face will always look like this?"
"Yes."
"Will it not affect my experience? What happened in the past thirty years or so, my knowledge, intelligence, work ability, moral standards and social relations, the papers I have published, the professional titles I have evaluated..."
"Nothing will be disturbed. Only your face changes. There is no grandmother paradox or butterfly effect."
"Meanwhile I'm going back a year and a half?"
"Yes, you will get the opportunity to spend these 547.5 Days again. Things that happened earlier will not change, but what happened in these 547.5 Days will not necessarily happen again. The future before 547.5 Days is not equal to the present."
"That is to say, it could be better or it could be worse."
"Yes."
"... Do you think it's effective? I mean... If you become more beautiful, you have a greater chance of getting love?"
"I don't know. But for you and your crush, I think so."
"Is it possible that the ending will be worse? In other words, it will be worse than now. Not only will I not be able to catch him, but what else might I lose?"
"This possibility cannot be ruled out."
"... I've decided. Let's get started."
"Okay. I need to state again that I only help people once. No matter what ending you get, I will never be able to take you back to your current life."
"I know. I've decided, let's get started."
"My hair became white with sorrow, and my heart was filled with sorrow for being away from home for a long time. I was even imprisoned, so I changed my appearance."
