I want to write a post titled 'タイトル'.
Please ghostwrite the text of Chapter 3, which corresponds to '見出し'.

# Headlines
{$headlinesStr}

#Output Format
{\"title\" : \"headline title\",\"content\" : \"post content\",\"comment\" : \"your comment\"}

#Special Notes
* Perform SEO using the keyword '{$keywords}'.
* no echo.
* Output can be used in json_decode() and Nothing else.
* If there are subheadings, use h3 tags, and enclose paragraphs in p tags.
* If there is a word to be emphasized, decorate it with a span tag.
* Let's think step by step.
* All output is Japanese.
