They could have stayed in Takara's house and lived happily as a family but it seems that he wanted to live with Kiyomine only. That is a huge hint in itself. I think everyone around including Ayako and Kou knew they probably love each other but didn't recognize this for themselves yet.
When Takara came back from Africa and Kiyomine picked him up at the airport...the way he hugged Takara and Takaram gripped onto to him with tears in his eyes to me says these two love each other. That expression to me said it all about them.
It would be nice if Abe wrote one more chapter... years later to see what became of them as adults.
I loved this magna. It was so adorable and emotional at the same time. I loved Arikawa and Misaki. I believe they were meant to be together. After the sad lonely life Misaki had it was like Arikawa was drawn to him to fill his heart and take away the lonliness. I really love this author. I also finished vol 1 of Ten Count...like wow.
I have a feeling that Ren will go to school abroad. Haru forgot about Ren for 5 years last time. Who knows how long it will take for Haru to get all his memories back of Ren and him being in a relationship. I also think we will see Ren a few years later all grown up... taller and looking very masculine.
It wouldn't surprise me at this point with him losing his memories again. There is no way that Ren would be able to stay around Haru knowing he could go back to dating women again with his memory loss. It would be too painful for Ren.
