WON'T WATCH AGAIN-Japanese

Just another 'you destroyed us but that's okay' drama.  Yes, a kid initially caused it accidentally, THAT should be taken into account, however, a family was destroyed because of it and the mother of the kid shamelessly took full advantage of that adding acid to a grievous wound...then has the gall to say it was the fault of the child from the destroyed family for her world crumbling when the truth came out.  We also have the fact that the kid grew up and as an ADULT decided that becoming a doctor was the best way to show he was sorry, rather than admitting to his actions and removing the blame from an innocent person?  Groan.  

The brother is also at fault for hiding it until he was forced not to, also as an adult...
