I thought they'd mention the dad more...somehow it doesn't seem finished...there was absolutely no mention of how the original couple is doing 10 years on!!
I agree with Anonymouse, it would been nice to see a little from the original couple. It seemed like Akio's brother completely disappeared from the apartment.
love it was soo hot also i though the older man would be on top and the 16 year old would be at the buttum lolzzz
