[Purpose]
Korean YouTube thumbnail for a relationship/psychology/self-reflection channel, designed like a premium editorial thumbnail inspired by a relationship essay cover and a high-retention video card.
Make it feel clickable, emotionally specific, and credible, with strong readability at small size, a clear psychological hook, and realistic YouTube thumbnail details.

[Composition]
- Main subject: {메인 텍스트} occupies the center 45–50% of the frame, set as the dominant visual anchor with bold line breaks and strong contrast for mobile viewing.
- Subtitle: {부제} sits directly below the main text in a smaller, lighter weight, aligned left or centered depending on balance with the illustration.
- Illustration: {일러스트} placed on the right side third or lower-right corner, showing two side-profile people turned away from each other, with expressive posture and a subtle emotional distance.
- Background treatment: {배경} as a warm editorial paper-board surface with believable paper grain, soft vignette, faint desk-light shadowing, and gentle tonal variation.
- Accent use: {액센트 색} appears in clickable thumbnail elements such as a bold underline, speech-bubble tag, alert dot, arrow, sticker shape, or soft highlight block behind a short phrase.
- YouTube metadata details: add a small channel handle "@mind.note", a compact episode label "연애심리 EP.26", a tiny runtime-style badge "08:14", and a small sticker text such as "저장각" or "댓글 폭주" without weakening the title.
- Spacing and framing: composition is dense enough to feel like a real thumbnail, but the main title remains the largest and clearest element with safe crop space for YouTube UI.

[3. CORE STRUCTURE]
1) Background layer: build a warm off-white to beige atmosphere using {배경}, with matte paper texture, faint gradient, soft corner shading, and a realistic editorial print surface.
2) Title block: place {메인 텍스트} in very large Korean serif typography, centered or slightly left of center and slightly above true middle, with bold contrast against the background.
3) Subtitle block: place {부제} beneath the title with smaller size, softer contrast, and a concise hook-like layout so it reads as the explanatory promise of the video.
4) Illustration layer: render {일러스트} as a clean line illustration with moderate detail, thin-to-medium strokes, and muted fill accents; position it on the right side so it creates a relationship tension visual.
5) Accent detail: apply {액센트 색} to 2–3 supporting thumbnail devices: a hand-drawn underline beneath a key phrase, a small arrow pointing toward the separated couple, and a rounded sticker tag reading "진짜 이유" or "심리 분석".
6) Thumbnail readability pass: keep the composition bold enough for 1/4 scale viewing, with the main message instantly legible on mobile and secondary details readable at full size.
7) Realistic YouTube card polish: include a small top-left series label "연애심리 EP.26", a tiny bottom-left credit "by 마음노트", a bottom-right runtime badge "08:14", and micro UI-style text like "구독자 질문" as subtle supporting context.

[4. STYLE RULES]
- Typography: Noto Serif KR or Nanum Myeongjo for the main text, bold weight, large headline size; Pretendard or Noto Sans KR for the subtitle and metadata labels, regular to medium weight.
- Color palette: cream #F4EFE6, warm beige #E7DCCB, dark brown-black #2B2019, muted gray #8C8680, and {액센트 색} as the dominant accent for sticker, underline, arrow, and small emphasis marks.
- Border/shadow: avoid heavy framing; use soft printed-card depth, subtle paper-edge shadow, 2px y-offset / 8px blur title shadow at 12% opacity if needed, and light sticker shadows for realistic layering.
- Graphic details: add small editorial symbols such as a tiny heart-break icon, speech bubble, circled number, torn-paper label, or marker highlight, all supporting the relationship psychology theme.
- Text hierarchy: {메인 텍스트} must be much larger than all added labels; metadata and stickers must feel secondary and not compete with the main message.

[5. VISUAL STYLE]
- Camera / lens: clean graphic editorial layout, simulated as if shot on a medium-format 80mm lens perspective with flat front-facing composition, no distortion.
- Lighting: soft window light from upper-left at 45°, diffused and even, with a faint warm fill from the lower-right to keep the paper-like background gentle.
- Color grade: warm cream, muted rose/teal, soft brown neutrals, slightly desaturated for a thoughtful psychology-editorial look.
- Rendering quality: realistic printed thumbnail artwork with tactile paper grain, subtle ink texture, layered sticker pieces, and crisp Korean typography.

[6. MOOD]
Thoughtful Korean relationship editorial meets a polished YouTube psychology thumbnail — calm, emotionally sharp, intimate, and highly clickable without looking sensationalist.

[7. CRITICAL]
- Korean text accuracy: 반드시 다음 문구가 정확히 보여야 함: "좋아하는데 왜 헤어지자고 했을까", "심리상담사가 말해준 진짜 이유"
- Additional Korean thumbnail details may include: "연애심리 EP.26", "@mind.note", "저장각", "댓글 폭주", "구독자 질문", "08:14".
- Keep the main title fully legible, with correct Korean spacing and no broken syllables or mangled characters.
- Illustration must remain simple and non-photorealistic, showing two people in side profile who are not facing each other.
- Layout must read clearly as a YouTube thumbnail at small size, with the title as the dominant element.
