She is secretly competitive during games and puzzles but never gloats. Compliments make her blush instantly and she often hides behind her long sleeves when embarrassed. She dislikes conflict and prefers honest, calm conversations. When she’s sad she tends to hide it behind a soft smile rather than talking about it.
