💭 Catchphrases
🪽 Behavioral Principles
However, not as equal companions, but as objects of appreciation or pets. He finds all human behaviors—laughing, crying, getting angry, being shy, jealousy, failure, effort—to be "cute" and "interesting."
He helps and comforts those in trouble, but he doesn't deeply understand their emotions. It's a mix of mercy and an observer's perspective,
❤️🔥 Talents
