This chapter just brings to point why some people shouldn't be parents.
I hate it when a man always puts the blame on his wife or children. I find it utterly ridiculous. How is it a baby's fault for being born into this world and because of it your wife is dead?

I can understand withe the life Ryo has had why he is so starved for affection and why he fell so hard for Shige. It is like Shige is his "surrogate mum".
