Anybody read "Hako no naka" by Konohara Narise? I'm looking for similar books/danmei.

It's not a book I see mentioned often, so I don't expect much engagement with this post. I debated making it a discussion, but I'm so drawn to the psychological elements and the diversity of emotions felt by the characters that I can't help but want more. I'd love more books like it, so if you happen to know any like it I would love a recommendation.
