Spoiler/rant
This is the most emotional, fucked up shit I have read in awhile. Where do I start, the lack of value for someone's life is a big one. That younger brother is a raging psycho and has no regard for other people's feelings. Then the boss/friend/lover is just an ass. How the he'll did the father not realize anything and the step mom/bitch blamed the older brother for everything. Like wtf was wrong with those people. I have never been more sad and angry reading a manga in my life
