I had read the manga and personally I quite liked it. So initially when I saw there was an anime released of it I was quite pleased and expectant. After watching till the 5th episode I was displeased and upset, they added scenes that were highly displeasing and thoroughly sickening. As well as the change of persona in the characters and they made the MC malicious in a few scenes and acting as if the people around him were mainly tools, which he did as well as in the manga but still cared about them.
Some scenes were highly unnecessary and quite sickening due to the acts preformed with those old and the child MC, I also found episode 4 quite displeasing as well.
