As all we know Arashi are the main personality for this show this year so rumors about one of them in the usual tanpatsu were out some weeks ago but now we know they are all true!
The title of the story will be: "Myuu no Anyo Papa ni Ageru" (I will give papa Myuu's legs);
it is based on a true story of Yamaguchi Hayato, a 25 years old man with a wife (that will be played by Karina, at her 2nd co-starring with Jun after Bambino!) and a 2 year old daughter, Myuu.
He has got the "CIDP" disease (info here), which hit every 100,000 person and is incurable.
A really challenging role for him because the disease is cronical and progressively you can't walk or use your arms and you can also experience breathing problem... it will be a real sad tanpatsu as usual ;_;
"Myuu no Anyo Papa ni Ageru" will air on 30th August (Jun's birthday ^_^)
