[When are Tenka and Sousei not bickering to be honest.... but he doesn't seem too bothered at the question. Rather Tenka just shakes his head and laughs lightly. At the very least, he can trust Kousetsu to always be direct with him, huh? Well, there are worse qualities for their newfound friend to have.]

I'm just playing with him, Kousetsu-kun. Don't worry about it.

[Then even as they're walking along, Tenka reaches out to jab at Sousei's shoulder, giving him a grin.]

Lighten up! We'll get that really spicy stuff you like. If you keep frowning like that then you're gonna worry Kousetsu-kun even more.
