Well the Rihoko fans will definitely be pleased with this arc. (not that there was any real doubt that they'd be fixing the lack of romance in Rihoko's arc back in season 1)
More of Junichi's classic hijinks; a little bit of helping out Rihoko with her weight concerns. Which means personally checking her physical fitness, of course. And in Japan, that means measuring weight, height..................and bust size.
Smooth as ice, Junichi.
A little contrast to how the episode ended; from his actions and statements, it actually looked like that guy might actually try something on Rihoko for a minute.
(I actually thought to myself, "where'd Amagami go??!!")
