This drama is just 3 episodes, so I cannot say there was much of story development, it is not fair to comment on that, but it did manage to show well how conservative Japan views same-gender relationships and marriages in mere 3 episodes. The attitudes of everyone - from the sibling himself, to his child, the child's friends, their parents, their school teachers, the ordinary people in the neighborhood, etc. - were all shown subtly in Japanese style.

It had good pacing, never a dull moment and well-executed. It also gave a warm feeling at the end when the Canadian brother-in-law returned to Japan, bringing together his Canadian family..

There was a little surprise at episode 3 about the brother's childhood friend though. At least it was a tiny surprise to me.

I would recommend this drama if you want to take a glimpse of how ordinary Japanese people view same-gender relationships.
