I'm participating in this discussion a little late (I prolly wouldn't even have looked at it if I hadn't been on a posting ROLL today XD), sry. But if I had a question...
I'd probably ask why in the world Ren and his family don't speak Chinese at all. I understand the Japanese when they're interacting with the other characters, but why doesn't Ren address Jun as "jie" and has to call her "nee-san"? (Of course, this is setting aside the fact that Paku Romi only speaks Japanese XD) And for that matter, whenever Tao family members speak to each other in private, it's all in Japanese. Why not Chinese/Mandarin?
Of course, this is probably an EXTREMELY stupid question because it's obviously a Japanese anime/manga so they should be speaking Japanese. I guess it's just because I'm of Chinese descent. That, and I'm running on four hours of sleep with nothing but cranberry juice and milk to sustain me...WHEEEE!!!! **explodes**
