Yossi on TV: designing a rider jacket and sharing beauty tips.
Yossi on internet: showing beauty products she uses; appearing/being mentioned ubiquitously in everybody's blogs (Makochan, Kemeko, Nakazawa nesan, Kaorin and Niigaki@radio)

Rika on TV: backpacking and trekking to third world countries, enduring harsh living conditions, making her already dark skin more sable.
Rika on internet: only one publicly known private pic with Kemeko and occasional - very occasional - cameo together with Yossi in Makochan's blog.

Before, Yossi was boyish, secretive and dorky,
and Rika was the Alpha girl: girly, feisty and pampered.

Now, Yossi's always dressed in white and pink and has grown her hair long. Rika has cut her hair and is often seen in black, sometimes with long-sleeved shirts as overalls.

(Me says...) Notice the switch?
