Ai-chan has been wondering, instead of honestly telling people that he's unemployed, why not tell people that he's a swordsman? It's not like they can check and he's way better than real swordsmen anyway. Would've saved him a lot of trouble,
@Aichan its probably because people know the characteristics of the [swordsman] job and so he can't get away with it, and if he lies about his job and its revealed as a lie then he could possibly get in trouble legally, so its easier to just say he's unemployed
