Sekai de ichiban papa ga suki [世界で一番パパが好き] I really love this movie. I have had a crush on Ryoko since this movie. That's how I began to watch Japanese movies and dramas.
I watched it in 2010, so I barely remember most of this drama content. Still, I know it's a really great drama and desperatly want to watch it again, with Vietsub or Engsub so that I can understand what they say...
Sorry for my bad English.
To me, it's a 10/10 drama.
