Not too fond of the explanation of "we let her die because of her father's religion", but the story was nice. And yeah, totally look forward to the father flipping out even more when he learn his daughter is lesbian. Would make for a fun extra chapter. XD
It happens, the jeovah witnesses refuse blood transfusions even if their relative is dying and sue the hospitals that do it anyway.
Is the christian minority in japan usually that fundamentalistic? And is the interpration of freedom of religion even that radical there? For example as far as I know .in Germany, if parents refuse that their children get's important medical treatment, the doctor is able to open a legal procedure so a guardian can implemented who takes the decision for the child. In extreme Cases parents can even lose the custody over their child, although all of this is only the ultima ratio. The wellbeing of the child in this country is always more important than the religious believes of their parents, although such cases are rather rare in germany. I don't know how the law in japan is exactly, but I know that they have a really strict understanding of the seperation of state and religion, so I can't really imagine that it would be legal to let a child not undergo a lifesaving operation because of religious feelings.
But this story wasn't really good to begin with. It felt really forcefully slowed and rushed at the same time. The drama was over the top and the characters have not much personality to begin with.
