You put my feelings into words. I hated every single one of these characters and absolutely LOVED the story!
I was not rooting for any one of them. Even Miki was starting to piss me off a bit before the reveal with the whole push-and-pull thing. Then the reveal came and I was like, yep, I do not like anyone here (tho it did seem he wanted to back off on the murder plan. Or like tatsuma says, he’ll start planning the murder again the following day, who knows)
What an insane storyline fr. I wasn’t able to predict where it was going at all

This is not the kind of stories one easily forgets. Not because the plot is particualrly well done or the art is especially beautiful or anything like that, but simply because there's this real "wicked" feeling to the characters. Miki and Tatsumi are downright nuts and evil.
I honestly don't feel sorry for anyone in this story.
Tatsumi, just like Miki said time and again, is a real villain and definitely has criminal tendencies. He's also violent, cold and obsessive. Totally not a good guy...And the way he was also using Ryouma by the end just shows how far gone he is.
As for Miki, I guess Karma got him.. If the woman had refused to leave her husband for him he should've walked away, what did he expect from cheating with a Yakusa's wife? no matter her circumstances! But instead he was obsessive and jealous and went as far as messing up Tatsumi and using him to plan to murder the guy..The worst thing is that I'm convinced that if Tatsumi had really killed the Yakuza, Miki would've definitely ran away with the woman and left him behind without a single hesitation.
And even the side characters are evil, The Yakuza is far from an angel. He's apparently a scumbag but the wife is no better either, keeping Miki around for emotional relief while refusing to leave her husband.
And Even Ryouma deserves what happened to him, kinda...The guy is weak, a pushover and a doormat who got in a difficult relationship and, in a moment of despair, killed a person..(reminds me of all those shooters we see in TV who spend their life taking shit from others, never standing up for themselves, only to mass murder people when they "break"!) He is unhealthy, pathetic, and WRONG!
Anyway...................I LOVE THIS MANGA!!! LMAO! All the bad people got bad endings!
