Something changed, especially in her eyes... or maybe he's just reflecting her own attitude and worrying too much.

[And then there it is again, another change but he follows this one a lot easier because he's just that good at knowing when he's being teased. Kotetsu stiffens up awkwardly, realizing what she's doing and so he decides to cross his arms over his chest and look off to the side in an exaggerated huff.]
