This manga started so good, then gone dark when this Neko appeared... aaaaand now its just bullshit is what it is.
No anger towards Neko after revealing all what hi did not even to her, but her friends (and she suffered years after that trauma), but now even justifying his behaviour? Really?
Nothing in the past dont give you a credit to own someone's life, manipulate it, blackmail people and threatened someone so you can be with this blacmailer. But author think that we need to sympathize him now bcs somewhere in the past something bad happened to him and somewhere inside there is something good in it? What the heck? I guess if he would regret it, apologize, confesses in his wrongs and asked for forgiviness - that one thing. But he is surely dont regret it and even do this over again - and in this character we must believe, that he is just dome poor lonely guy? Just f*ck you, author, go f*ck yoursel with this bullshit writings of yours.
This is just one of the worst direction you can ever imagine, where this manga could go after introducing this Neko-dude to the readers - and it goes this way - to the bottom of interest.
