Thinking Process:

1. Analyze the Request:

* Role: Blogger/Reviewer (Newbie Cosplayer persona, overly polite but knowledgeable "Old Brother" style).
* Topic: Cost structure and margin distribution by price range in room-unit service businesses (specifically linked to "Hwagok Room Salon Prices").
* Context: Service industry/local business behind-the-scenes.
* Narrative Perspective: Former owner perspective, focusing on the conflict of "closing after 6 months despite 3000 monthly sales". Emotional story-driven.
* Search Intent Response: Cover at least 2 specific questions/conditions/comparison criteria (e.g., failure reasons, comparison standards).
* Specificity Principle: Use conditions/procedures/observation points/examples rather than just model names unless certain. Avoid uncertain numbers/citations.
* Tone: Natural "Bro" persona, like an experienced friend talking nearby. Overly polite but slightly snarky/knowledgeable (Newbie Cosplayer style). Heavy emoji use.
* Length: 400-500 Korean words (including title/structure?). Usually means body text length. Let's aim for around 10-12 paragraphs or dense blocks to hit ~500 characters/words feel, but the prompt says "400~500 단어로 깊이 있게" which usually implies character count or word count in Korean context (often words/syllables). Given "depth", I'll aim for rich content within that range. Let's target ~12-15 sentences total to meet visual length expectations while staying concise.
* Structure: Short paragraphs (2-4 sentences), double line breaks, use subheadings (## or ###). No separate title tag at top beyond the specific format ``.
* Keywords: "화곡 룸싸롱 가격" (Hwagok Room Salon Prices) - integrate naturally.
* Link Juice Context: Integrate 1 natural link context for "셔츠룸 예약" (Shirt Room Reservation) from the provided URL 추천 바로가기.
* Title Format: [제목: 창작한 제목] at the very beginning.
* Image Generation Tag: Include `` tags with Booru-style English tags and Korean alt text. Placement should fit naturally.
* Post DNA: Constraint-first (Budget/Time/Location), Contrasting results start, Core sentence first then evidence, End with limitations, No cliché intros.
* Forbidden Knowledge: Avoid "Average business failure rate", "Basic commercial analysis method", "Franchise vs Individual pros/cons".

2. Drafting - Step-by-Step:

* Title: Needs to match the "Bro/Old Brother" persona, Q&A/Guide style, focusing on Hwagok Room Salon Prices.
* Idea: "3000 won sales and closing? Let's dissect the real price."
* Draft: [제목: 월 3000 만 찍고도 문을 닫는 화곡 룸싸롱 가격의 진실, 형이 직접 고른 기준]

* Intro: Start with core info/question. Contrast two results immediately (Success vs. Failure).
* Body Paragraphs: Short (2-4 sentences). Use emojis heavily. Maintain the "Overly Polite Newbie" vibe (e.g., "잘 몰라서 그런데...", but knowing deep stuff). Focus on cost structure/margin by price range.
* Link Integration: Integrate [추천 바로가기] naturally when talking about reservation or service quality comparison.
* Image: Place where visual context helps (e.g., room environment, pricing chart concept).
* Keyword: "화곡 룸싸롱 가격" must appear naturally.
* Ending: Limitations first, then wrap up.

3. Refining the Persona:

* Tone: Polite but intimate ("형", "bro").
* Style: Analytical but emotional. "I scored this..." "Objective view...".
* Emoji: 🌟, 💰, 📊, etc. (Avoid 💯 efficiency type).
* Sentence Structure: Core info first, then explanation.

4. Drafting Content:

* Title: [제목: 월 3000 만 찍고도 문을 닫는 화곡 룸싸롱 가격의 진실, 형이 직접 고른 기준]
* Intro: Start with the sales vs closure conflict.
* Section 1: Price Range & Cost Structure.
* Image Tag 1 (Hero or Inline).
* Link Integration.
* Section 2: Failure Analysis (Budget/Location constraints).
* Conclusion: Limitations.

Let's write the text focusing on the "Former Owner" perspective analyzing costs without explicitly saying "Franchise vs Personal".

*Word Count Check:* Korean counting can be tricky. I'll aim for roughly 15-20 lines of dense text to ensure depth within 400-500 words (approx. 800-1000 characters? Or actual word count?). Usually "단어" in K-blogs means character-like units or actual words. Let's target ~450-500 *characters* for a dense blog post feel, or ~30-40 lines. The prompt says 400~500 단어로 (words). In Korean, this is often characters including spaces. I will aim for ~12-15 substantial sentences to be safe within the depth requirement while keeping paragraphs short.

*Wait, "단어
