There was a very practical reason why Yu Seol-Ha lived in isolation.
It was not because Rakshasa hated company, although she had little tolerance for most people.
Nor was it because she needed to hide, since there were very few creatures in the world capable of forcing her to do anything.
The problem was her personality.
Yu Seol-Ha had never learned how to live halfway.
When she trained, she trained until she destroyed her own body.
When she taught, she demanded that her disciples reach their limits.
When she cared about someone, she became intensely protective.
When she hated, the idea of moderation simply disappeared.
Her patience had always been short, and thousands of years of absolute power had done little to develop self-control whenever something truly managed to pierce her emotional defenses.
That was why her castle remained isolated.
That was why she kept few servants.
That was why she rarely participated in the Kingdom's political disputes.
