He felt it all rush against him, each memory clinging on to his head. Each time the pain got worse and worse for Kamui. He felt as if he was about to break, he wanted to scream and just let it all out. And Subaru was there, always there to give him gentle words he needed so much. He needs Subaru now. Subaru doesn't lie, yet Subaru is always nice; no matter how harsh the reality. As Kamui lets his pain out, Subaru comforts him. And when Subaru needs the same, he does what is right. This is them; this is the bond between Subaru and Kamui.
Subaru looks at Kamui as they continue they're conversation. Kamui gives his angst, and Subaru listens with all honesty. But now, Kamui is in pain. A different kind of pain, he is in shock at this realization.
"Subaru ... am I moody?"
Kamui was very confused when Subaru blurt out laughing.
