The drama is neither happy nor sad, but it is full of reflection. The 14 years old girl in pregnant... It sounds terribly. Miki gave a baby, though everyone has objection. I see her future in black colors, but who knows... I admit she had exceptional parents, who could accept that choice. Especially mother. An oasis of calm. It was very unrealistic, but finally - it's fiction.
In Japan, at least the abortion isn't forbidden, so there always exists a rescue answear this situtation. Maybe it's not easy, but there is always better to have a choice.
