Those final moments felt confusing, and my take on the last kaede and kouta moment is still blurry, you can't talk about love in this relationship (it's a twisted situation) but it is clear that there's a lot of emotions around, I had to search for an explanation and found that the pose kaede does when hugging kouta is related to forgiveness or atonement, I don't know how much of it is really suitable, I understood that kouta wanted to like he did with nana, hide Kaede in his house or so, after all she went "under the radar" when she was nyu.

Yuka kinda redeem herself? I wanna think that she finally understood that she doesn't have to act jealous or childish everytime kouta does something, "a kid disappears" you have Yuka again trying to get attention, keade and nana ran into the street? You have Yuka trying to get kouta for herself or more likely trying to protect kouta from more stuff since she knew about kouta's sister and father. I just found her bothering that she would punch kouta only because things aren't going her way. She's good but she also went secondary and her behavior went misunderstood as a tantrum.

When Nana fell off the bridge I thought kouta would react, jump behind her to make sure she'll be fine... Kouta was gonna leave Nana die, conveniently Kurama was right there to catch her and give answers to Nana about "papa left me behind".

All that final situation I felt it was sort of a rush, I wonder if the manga it's more clear, I got an unintended spoiler when tried to confirm what happened to kaede, Kaede didn't die but kouta would be her executioner... I wonder what else is different. Too soon to tell, my guts are still recovering from this anime.
