fukumean's manga / #Supernatural(8)

this was one of the best i've ever read. it was so muah. It has actual plot, i love how it surrounds the idea that love is ur demise nd shit, and it's written so beautifully + art style is so buss. Though i wonder, why was Walds shade so vicious? what did he regret so much? was it regret that he loved J, that he love J as a son or found himself loving J romantically which made him resent himself? i would think he wanted to die , so maybe he said J's name, but i feel like im left on an open end here that i can't really interpret for myself. help?? thoughts???
