Episode 5 completes singer Nana's past story. Much of episode 6 shares animation with episode 1. In fact, I felt like I was watching a rerun. I guess it will start moving forward again in episode 8 since we've gone through their past lives and they have more-or-less completed moving into their new place.
Flashback, hence the desaturated colors. Do they have any idea how filthy the place becomes when they smoke indoors?
Considering the price I'm paying for these DVDs, I'm impressed with the art quality.
Just at the end, somebody forgets how to draw! I hope this is just a glitch and not indicative of what's to come.
