### **English Summary: Emotion-Driven System Design under 2D Constraints**

#### **Core Design Elements**
1. **Storyboard Emotion Theater**
- Zone division by emotional types (sofa/training/tavern areas)
- Present interactions through comic panel layouts
- Simulate spatial depth via angled dialog boxes

2. **State Machine Behavior System**
- 6 preset behavior states (rest/training/socializing)
- Time/event-driven state transitions (auto tavern events at night)
- Reuse battle animations for interactions

3. **Player Perspective Control**
- Double-tap characters to activate bidirectional dialog trees
- Swipe to switch between Observer/Roleplay modes
- Long-press for inner monologue透视

#### **Dynamic Emotion System**
```mermaid

A[Player Login] --> B{Time Check}
B -->|Morning| C[Trigger Training Event]
B -->|Night| D[Trigger Secret Dialog]
C --> E[State Machine Update]
D --> E
E --> F[Interface Redraw]
```

#### **Emotion Enhancement Strategies**
- **Visual Tricks**: Achieve spatial perception through layered sprites
- **Sound Coding**: Custom breathing SFX with 3 frequencies per character
- **Choice Ripple**: Critical decisions affect next 3 dialog option pools

#### **Implementation Path**
1. **Asset Reuse**
- Convert battle effects into emotion particles (e.g., sword glows → heartbeat特效)
- Implement 20 micro-expressions using same sprite sheets

2. **Low-Cost Dynamics**
- Dialog shake algorithm: `x = sin(time*10)*2`
- Emotion color system: RGB linear gradient by affinity level

3. **Player-Driven Ecosystem**
- Weekly "Emotion Puzzles": Repair broken relationship lines
- Unlock "Memory Corridor" to review choice impact trees
