Original Japanese:
[paste your Japanese draft here]

Requirements:
1. Choose the right honorific, humble, and polite forms for the situation; do not overdo it and sound distant.
2. Keep the meaning and paragraph structure; the result should sound natural, not like textbook examples.
3. Explain each change and why, so I can write it correctly myself next time.
4. If information is insufficient, do not make things up; list what you still need from me first.

Output format: the full rewritten text first, then a table with Original / Rewritten / Reason.
