This is a complicated topic on one hand the author is a creep who deserves to be incarcerated, was he drunk or druged (not defending him, just wondering how he can screw his life so much while being in a sane state of mind), but in the other hand his work is not a fault of his actions, even more this work given that it was a collaboration between 2 people, I hope people bash only on the author, but leave the artist and this manga out of the line of fire.
Sad that it ended, glad that I could readed, hoping the artist can make a sequel (doubt it) or she can atleast keep working and make something even better
