It makes sense that Ajiki is the one orchestrating this. He knows Maria is targeting him and he can't trust Okaya to keep him safe. I underestimated the token fat guy for being a useless pawn and eventual casualty. It turns out that Ajiki is just as sociopathic as Okaya.
You realized the cruelty you inflicted on everyone, but instead of going back in time to stop yourself from committing these acts your solution was go back in time and recruit the other alliance members you killed to fight an unwinnable war? Man Han Taesoo, you really are a dumbass.
So the chief was pissed that the Detective was stealing their glory, and is trying to frame an (somewhat)innocent man of murder just to restore the public's faith of local law enforcement. What a pathetic asshole.
PLEASE PLEASE PLEASE KILL AZUMA!!! SHE FUCKING SUCKS!!!
