It’s an amazing drama ..I loved it a lot especially its boldness in raising the idea of whether Japan could have been unified without cruelty, violence, and massacres
What puzzles me is that Makiko doesn’t seem to have a strong enough motive to commit such a crime. Even if her son was denied admission to that school, it hardly feels like a convincing reason for murder. Her son doesn’t appear to be the culprit either — he asks Junichi whether he’ll be arrested just for stealing, and if he had committed the crime, that conversation wouldn’t have sounded so innocent. So far, the direction of the story — where it seems Makiko is covering up her son’s crime and then Naoto is covering up hers — just isn’t convincing to me.
The rest of the details would spoil the experience for you
