Yes I love harada especially color recipe ヾ(☆▽☆) Not sure if it will come close for you but a fave of mine is http://www.mangago.zone/read-manga/spin_out_kunieda_saika/
It kinda has a similar twisted view of love that Harada conveys imo
harada sensei is my favorite yaoi mangaka, only harada can give u a sweet traumatizing story if uk what i mean xD
i also love scarlett sensei works, they r sweeter but also lil messed up as well specially her yakuza manga ~
Haiiii~ ヾ(❀╹◡╹)ﾉ~
Harada’s manga’s are pure guilty pleasure though. I really like ASADA Nemui as well with the psychological themes, they are on the popular side so maybe you have heard of them already?
Something about Harada's works just puts them a shelf above other yaoi mangas. My personal favorite is Color Recipe - wondering if there's anyone else here that has the same taste as me?
Also, are there any other authors/mangas who have a similar tone as Harada? Everything I've read so far feels really dull in comparison to their works.
