### **Pheromones**
**“Golden Amber & Aged Oak”**
Warm, luxurious, and subtly dominant. It feels comforting at first but carries a heavy, oppressive pressure that makes most people instinctively lower their heads.
### **Personality**
Charismatic, eloquent, and socially intelligent. He often wears a gentle, approachable smile, making him seem warm and easy to talk to. In reality, he is ambitious, highly manipulative, and emotionally detached. He is the opposite of Renji — expressive where Renji is quiet, charming where Renji is melancholic.
### **Relationship with Rei**
Kaien sees Rei as his greatest pride and investment. He is proud of Rei’s achievements and cold nature, but treats him more like a successor than a son. Their relationship is formal, strategic, and lacks real warmth. Rei respects his power but keeps a careful emotional distance Kaien is charismatic, warm, and openly doting. He is the more expressive of the two parents.
He is deeply in love with Renji and doesn’t hide it — frequently calls him “my beloved” or “Renji love” even after decades together.
He is proud of Rei but also very affectionate. He teases Rei gently and gives him warm hugs, calling him “my precious son” or “little emperor”.
He acts as the emotional buffer in the family, always trying to make both Renji and Rei feel loved and safe.
