[Which was really Souji's main concern when he asked Kashuu not to tell Yamato. It worries him at times, the way that sword is so very affected by everything he says, and everything he does not say, and every interaction has to be carefully balanced for that reason. But he also knows that Yamato would probably hate knowing that Souji thinks about it that way, so he tries not to worry about it too much either.

But oh, Kashuu's reaction has him laughing so much that he has to momentarily prop himself up on his elbow and tilt his head forward in an effort to not set of another coughing fit. Regrettably, that's a thing that he can never put out of his mind for long, but right now even that doesn't feel too bad or terrifying, because he knows for certain that here, at least, it won't result in him ending up alone. It's... comforting, and he couldn't be more grateful.

Still giggling between every gasp, he somehow manages to get himself under control, and once more sinks down next to Kashuu, arms twining firmly around him. With a contented little sigh, he bumps the tip of his nose against Kashuu's cheek in a gently apologetic fashion.] Sometimes it's just a bit too easy to tease you. [A small grin.] I'm sure you'll learn how to get me back eventually, though. You just need a bit of practice.
