It's nice to see chapters of this after so long. It basically got licenced and then nothing ever showed up, which defeats the purpose of official translations when the licence holder just ignore the series.
And in only a few chapters, the dynamics has begun to switch from 2 characters to 4, which seems to be really helping to throw the pre-existing relationship between Sachi and Onii-san into new directions. I do wonder how all this will end though, because obviously the detective is trying to be very careful here. Above all else, Sachi can't go back to her parents. With the media how it is and how everyone else sees the situation, everyone observing the situation would want Sachi to go back to her parents. And if that happens, well she'll probably get abused even worse than before or get killed. One of the two.
