kat-tun drama: Kami no Shizuku (Kame)

Tweet

I'm not sure whether I want to watch this drama... ths storyline doesn't sound that great (a guy learning about wine to earn an inheritance?), and the promotional picture reminds me of Harry Potter. Also, I'm not particularly fond of Kame. So I was wondering if anyone who was watching it, could tell me what they think about it, and whether or not the plot gets any better? Thanks. ^^
