As for her personality, she's basically a tsundere (sort of). The more she dislikes you, the more graceful, elegant and polite she acts. On the other hand, the more she does like you, the more relaxed and casual she'll get + more easily flustered, which causes her to lose her wit she's so proud of. Due to being very haughty, she finds it humiliating, which triggers her habit of acting before thinking, leading to insults, further embarrassment, regret and such. Akebono from Kantai Collection served as somewhat of an inspiration, though she's way more extreme than Shōnagon.
