I liked this drama but I hated the amount of illogical behaviour from some characters and the unnecessary obscurity of the story.

I know it's discussing a very serious issue here but the way the characters handled the abuse matter is so stupid, providing little to no solutions, none whatsoever to anyone who is involved.
What made things even worse (which is a personal matter but still) was the little kid's behaviour and his mum's lack of brains, I know he is a child and he is a wounded one but he was so spoilt like his mum which made it slightly harder for me to sympathise with them. I'm not saying I didn't wish for them to be happy, it's just that I wasn't particularly moved by their story, I had a straight face all the way.

I still loved Hiroto tho, and his selfless character, slightly annoying but I still loved him so much
The transition in the two brothers relationship at the end is the only thing that made sense to me as it's a necessity to both.

I won't say much because it's not necessary, but imho there are other dramas that handled many serious issues in a better way.
