The author note said @jeongsim267830 but I didn't check it
I found it thanks^^
The artist isn't the author, and it looks like this is the author's only work (the artist also drew for "My Ghost Diary" (bl)).
I really love the story and the art style is so gorgeous I hope in future we got to see more of this artist work in good stories.... If anyone knows the artists X account share with me(〜￣△￣)〜
