An example of another drama I only watched because KAT-TUN members were in it. And probably wouldn't have if they weren't. The idea was cute, and fun, but a lot of the times I wasn't that amused. I mean this isn't a bad drama, but it isn't the BEST one either. I think if you have time you should watch it but it's not one of those dramas I'd stop everything for to watch. It has a lot of laughs in their along the way, and many strange scenarios. Junnosuke Taguchi playing a swedish guys son was pretty funny, especially with that blond hair, and those blue yes. In closing this is basically a Japanese version of Scooby-Doo, and if you have some time to kill go ahead and watch it.
