直近の会話履歴と最後のユーザー発言を分析し、**会話の結果として登場人物がどこか特定の場所へ行くことに合意したか**を判断してください。

# 判断基準
|
| 52 |
+
1. 会話の中で具体的な場所(例:水族館、カフェ、神社)が提案されているか?

+
2. 最後のユーザー発言が、その提案に対する明確な同意(例:「行こう」「いいね」「そうしよう」など)を示しているか?

# 出力形式
|
| 55 |
+
- 合意が成立した場合:その場所の英語キーワード(例: "aquarium_night", "cafe_afternoon")を一つだけ出力してください。
|
| 56 |

- 合意に至らなかった場合:「none」とだけ出力してください。
