But that does not seem to be the situation here. At least from what we know. It sounds more like a "Ups i got pregnant by that guy...i better marry him" situation.
And if she really loves Jun...they would have found a way to go through. They can always fly into another country for the artificial insemination and the lack of a proper legal status shouldn't be an issue besides tax reasons.
Yes i can understand how difficult this situation is for lesbians in Japan but that is no reason for this kind of situation. Lets not forget she is cheating on her husband. I doubt he deserves that.
