### 日记输出示例

```text
Secret Diary — Day 417

He filled me again before sunrise. No apology. No eye contact.
Just another bitter liquid and the soft panic of a person
pretending deadlines are a lifestyle...
```

中文辅助：

```text
秘密日记 — 第 417 天

天还没亮，他又把我倒满了。没有道歉，没有眼神交流，
只有苦咖啡和一个假装 deadline 是生活方式的人……
```
