Gray Plains is actually a "quasi-dark" character, but it is fundamentally different from the real dark character.
Gray Yuan Wai is a mysterious, elegant, and fatal attraction to the male protagonist, but unlike the true dark characters, she is not bloodthirsty and crazy. When the author created this character, he not only gave her a dark shell, but also gave her a pure white core, which required a lot of extra pen effort to describe her mysterious, elegant and other attributes.
And the author did this because he wanted to make the core of Gray Plain Mourning pure and spotless, even if there was a risk of tearing and a lot of extra effort. Such a gray plain mourning is not only mysterious and elegant, but also has a fatal attraction that makes it impossible for people not to dislike her.
In the end, the author presents us with a dark shell and a pure white core, and the two parts are harmoniously unified in her, so that people will not feel torn at all.
Gray Yuan Wai is the author's most special existence, her image is both mysterious and elegant, dark and pure white, this image also makes us full of love for her.
