"BLACK. WHITE. GREY." illustration book probably about to be cancelled...? Why...?

Kuroi Kai said that he's been feeling too depress to think about completing the illustration book. For some reason, I'm not so sure why. He wasn't even clear with his reasons at all. Hopefully he's not going to cancel his plans or AKABUMI will not have any books to publish...

He's been isolating himself a lot lately. And I thought that he purposely did it just to get his work done. 

So hopefully he's not really going to give it all up. Otherwise AKABUMI needs a better artist to replace Kuroi Kai. Otherwise, he should be fired from AKABUMI... But firing Kuroi Kai from his own company...?
