Sorry for the double posting, but this doesn't really go with my previous post.
Someone up there must really like the combination of Nakayama Yuuma and Morimoto Shintarou, because Johnny's Net has updated, and added someone to the cast of that new FujiTV summer drama - Shintarou.
...yes, Nakayama Yuuma with Morimoto Shintarou yet again.
There are no news articles about this around, so there are no additional details whether or not they are playing siblings again.
Well, either way, Shintarou's pimping continues then.
