Every time I'm in the mood for some dark themes, harada's work is my go to. For this one, whether you liked it or not, one has to admit that it really is well written. Specially the psychological aspect of it (which is what I love about all of harada's work that I've read). I've read other artists/authors who try to experiment with psychological BLs before and it is either too unrealistic or exaggerated even or its lacking in some way but Harada manage to find the balance wih their work(a comment below explained this better).
