Well, Kai made the building blueprint, and that one is full of his usual life tired banter in all the info descriptions. He's passionate about his profession, software, but his workplace makes it very hard to produce things . He's treated mostly as a computer literate secretary by his extremely computer illiterate boss, and he's constantly ordered to spend his time doing things that are not really his job (hence the lack of enthusiasm). He didn't make the town map, though - maybe that didn't come across very clearly. It's a regular tourist fold-out town map that he grabbed somewhere in case the protagonist would want it. And if the protagonist expresses gratitude (if he's enthusiastic about his arrival), Kai will downplay that he made a kind gesture because it's just become second nature to him to be irritable and sassy. It's how he's coped with his miserable work life. All this should come across more clearly as the story unfolds :)
