Bab 175: I didn't ask for this weird big sister

"Now, Honey, let's go have some tea with my friends," she said with a very nice smile, pulling me gently but insistently after we were done bidding goodbye to Natha who had to meet with the important people of this city.

It wasn't like I had anything to do, so I just let her bring me further into the mansion. "Ah, the one who lived here too?" 

"Uh-huh," she replied with a small chuckle, and I could hear Arta let out a sigh behind me, which got me even more curious.

Who exactly were these people? It seemed like Natha used to visit them in the past, but for what purposes? Business?
