There are really two plots running through this. The front ordinary plot goes through the normal lives of the two girls with chemistry explosions, shopping expeditions, and winning volleyball games. The other plot is almost a gothic mystery surrounding the flowers, Tomomi and Mikage's powers, and the two twins halfway around the world in England. I haven't seen them repeat one yet. When coming out, there are various shots of the two twin singers posing as Tomomi and Mikage.
Closing credits are of the two singers performing the closing song against an animated background.
One thing I've noticed about Orange Road is that it is less serialized than most TV series are today. When you need to knock on wood is when you realize the world's composed of aluminum and vinyl.
