Thinking Process:

1. **Analyze the Request:**
* **Role:** Long-tail Intent Hacker (Q&A/Step-by-Step), specifically a "Hermit Collector" (은둔형 수집가) with an "Old Boy/Bastion" (반골기질형) personality. Deep knowledge, low social activity, obsessed with archiving rare info, contrarian views ("A" -> "B"), natural integration of character traits without explicit recitation.
* **Topic:** Edward Snowden's NSA Prism Program Slide #7 (Uncovered/Untouched by Media). Context: Declassified documents / MKUltra fact-checking.
* **Subtle Business Keyword Integration:** "여의도 마사지 내돈내산" (Yeouido Massage Paid Review) must flow naturally, not like an ad.
* **Perspective:** "Ex-Intelligence Analyst" analyzing the meaning of intentionally omitted page numbers in public documents. Emotional narrative.
* **Structure:** Diagnostic -> Execution -> Failure Prevention (Problem Diagnosis, Execution Steps, Failure Avoidance).
* **Format Constraints:** 400-500 Korean characters per paragraph? No, total length 400~500 words. 2-4 sentences per paragraph. Double line breaks between paragraphs. Use Markdown subheadings (`##`). No main title at top (use `` format for the first line).
* **Image Tags:** Specific Booru tag format with weights, natural language alt text in Korean, specific placements.
* **Post DNA:** 1bd07a49 -> Comparative Journey (Two paths to same goal), Failure Example Reflection. Intro like a quote from the field. Rhythmic sentence variation. Ending suggests next step, minimal CTA.
* **Keywords/Context:** Slide #7 of Prism, MKUltra context (obscure info), Ex-Intel perspective.
* **Voice:** Cool, collected, slightly contrarian, knowledgeable "bro" persona.

2. **Deconstruct the Content:**
* **Core Subject:** Snowden's Prism Slide #7 (Deep Dive/Untold).
* **Business Keyword:** Yeouido Massage Paid Review (Needs to link to "gathering info", "relaxing after work", or "hidden details").
* **Perspective:** Ex-Intel Analyst. Focusing on the *omission* of page numbers.
* **Structure:**
1. Intro: Quote-like field start, Slide #7 mystery.
2. Body: Analyzing the omission (Comparative Journey: One path = Media's shallow view, Other path = Analyst's deep dive). Link to "Yeouido Massage" as a metaphor for hidden comfort/details or actual context if possible.
3. Conclusion: Next small step, not heavy CTA.
* **Image:** Hero placement (Slide related/Intel related), maybe inline about the massage keyword connection? The prompt asks for `` tags where needed. Let's put one at Hero and maybe one about the "massage" context if natural.
* **Word Count:** 400~500 characters total is tight for deep analysis + images + specific structure. Wait, 400-500 *words* (단어) or *characters*? Korean usually counts by characters (자). Let's aim for ~450 Hanja/Hangul characters total including spaces/punctuation to be safe, but since it says "400~500 단어로 깊이 있게" (deeply with 400-500 words), in Korean context, this might mean sentences or short paragraphs. Usually, blog posts are measured by characters. Let's target around 450-500 *characters* total for a punchy post, but "단어" often implies word count equivalent. Given the paragraph constraint (2-4 sentences per paragraph), 3-4 paragraphs + title = ~10-12 sentences.
* **Keyword Integration:** "Yeouido Massage Paid Review". How to link NSA Slide #7 and Yeouido Massage? Maybe as a metaphor for "finding hidden details" or "recharging the mind after processing data". Or literally mention it in the context of where one goes when info overload hits. Let's make it subtle: "When analyzing raw data like Prism, sometimes you need a quiet corner... like the one on Yeouido."
* **Image Tags:** Need `placement`, `alt` (Korean), `Booru tags` (English, comma separated, weights).

3. **Drafting - Step-by-Step:**

* **Title Line:** `[제목: 창작한 제목]` format. Needs to match "Yeouido Massage Paid Review" type guide but with the Slide #7 theme? No, the topic is Slide #7, keyword is Yeouido Massage. So the title should bridge them or focus on the main topic with the keyword as the hook. Let's make it: `[제목: 스노든 슬라이드 7 장이 말해준 건 여의도 마사지보다 더 깊었다]` (What Slide 7 Said Was Deeper than Yeouido Massage). Or more guide-like: `[제목: 여의도 마사지 내돈내산, 그리고 정보기관 분석관이 본 프리즘의 숨은 페이지]`. Let's go with the latter to fit the "Guide" type.
* **Intro:** Ex-Intel quote vibe. Focus on Slide #7 omission.
* **Body 1 (Diagnostic/Comparison):** Media view vs Analyst view. Page numbers matter.
* **Body 2 (Keyword Integration):** Why does this fatigue happen? Mention the Yeouido Massage as a grounding point for researchers.
* **Ending:** Next step.

* **Wait, check constraints again:** "400~500 단어로 깊이 있게". In Korean NLP tasks, '단어' often means characters (자) or words. Let's aim for ~12-15 sentences to hit the character count range without fluff.
* **Image Tags:** 1 Hero + 1 Inline maybe? Or just 1 Hero. Let's add one inline near the keyword context.

4. **Refining Voice (Hermit Collector/Ex-Analyst):**
* Use words like "아카이브", "패치", "오버로딩", "숨겨진".
* Contrarian: Media says X, Slide #7 implies Y.
* Tone: Calm, slightly tired but sharp.

5. **Drafting Content (Mental):**
* Title: `[제목: 여의도 마사지 내돈내산, 그리고 정보기관 분석관이 본 프리즘의 숨은 페이지]`
* Para 1: "현장에서는 데이터가 끊기지 않아야 한다"는 말로 시작. Slide #7 은 보통 보고서를 넘기는 부분인데... (Slide 7 is where reports pass...)
* Para 2: Media looked at metadata, we look at the blank space. Like MKUltra but digital.
* Para 3: When brain gets heavy, need reset. Yeouido massage helps focus like a clean room.
* Para 4: Final tip. Check one more line.

* **Wait, Image Tags:**
Hero: `
```
Wait, the prompt says "다음 형식으로 이미지 태그를 출력하세요". It shows ``. Then lists tag rules. I will wrap tags inside or just after.
