But you're mine

TOH

'I wonder if she realizes what she is saying. Doesn't she remember how she told him before, that a perfect relationship doesn't exist. That a relationship is better where there are arguments as well as joy. A relationship that brings out your strength and weakness.'

Toh knew Sumire and Yuhi hadn't fought since that time during the boat journey to Sumire's home. It's a good thing there hasn't been any more conflict between the two. Last time he was in the middle of it all, and it was difficult to watch.

It was difficult to watch because he saw how similar the two were. He finally understood why everyone in the underworld thought they were together. It's because they are practically mirror versions of each other, down to their fighting styles, to their insecurities and likes and dislikes.
