Thielle's story was actually not so complicated, even somewhat cliché to some extent.
Since it was the tale of a young girl who had been rejected by those around her from birth and who struggled to gain their acceptance.
In the story, the girl was treated as a monster by those around her from a young age and thus experienced the harshness of the world.
People around her feared her.
Her parents were either always away from home, or they never looked at her with the eyes of a parent but as if at an unwelcome aberration.
Because of this, the girl never had anyone close who she could confide in; loneliness, emptiness, solitary, and darkness were her only companions.
Of course, nobody dared to abuse her.
Precisely because they treated the girl as a monster, the people around her were unwilling to get close to her, let alone provoke her—that was something only a fool would do.
