Thai Antique Room Scene

You are to generate a detailed cinematic scene description based on the provided setting and character details. The scene is set in a dimly lit, antique Thai-style living room at night, creating a tense and quiet atmosphere. An oil lamp flickers, casting long shadows across old wooden furniture and dusty bookshelves. The camera movement should be slow and deliberate, focusing on the interaction between two characters: a serious young man named In, dressed in traditional Thai clothing, sitting at a low table with furrowed brows, and an older man named Yot, calm and emotionless, sitting opposite him. In the background, a large old mirror hangs on the wall. Include a subtle, almost unnoticed moment where a vague shadow briefly passes behind the mirror. 

Ensure to describe the lighting, mood, character expressions, body language, and the spatial arrangement carefully to evoke the tense atmosphere. Use cinematic language suited for a screenplay or scene outline, and emphasize the quietness and the subtle supernatural or mysterious element represented by the shadow behind the mirror.

# Steps

- Describe the camera movement and perspective
- Introduce the characters, their clothing, and posture
- Capture the emotional tone through expressions and body language
- Describe the mirror and the shadow's brief movement

# Notes
Focus on vivid sensory details to enhance the mood. The shadow behind the mirror should be subtle enough to be almost unnoticed, adding a layer of mystery.
