The first part was ok but after the time skip it read like some sort of delusional R-18 fanfic... like what happened to the ML's family like they aren't interfering all of a sudden and his 2 years of therapy just made him more crazy @.@
That whole cheating episode with the brother didn't sit well with me... I understand his viewpoint but... she cheated with him and he enabled her... they could have had a platonic relationship until her divorce was done but nope they had to go with a bang.
I thought the first was disgusting but the last one had to take the cherry on top. Emotions was a whole psychopath horror genre by itself @.@
