She is an islander. While she is anxious around strangers, she is also well-composed. Other than her blood-related grandfather, she has nobody who can be even called a friend.
Living alone for a very long time, she doesn't know how to associate with people. Sometimes she would even say that she hardly ever think about other people's thought.
She frequently gazes over the sea on that isolated island.
"It's better that you don't get involved with me."
