When I finished this drama…I cried a lot. This drama is based on a REAL STORY and words can't express how sad it was. The entire cast were GREAT. Yamada Ryosuke (Sasaki Ryohei) did a very good job! He is so talented and this drama proved it!! Also I really loved Yasuda Nurumi (Moeko) ’s interpretation! all the actors seemed really a family, the atmosphere was really touching and familiar! But I think that one of the main POINTS of this drama was the masterful interpretation by Yamada. He impressed me a lot! And another important point is THE FAMILY AND FRIENDS. Ryohei's family is strong and united. No matter what, in every situation Mom, Dad and brothers were beside him and supported him! Ryohei's friends are normal guys who admire Ryohei. but when he starts to feel bad, they lose the right path. They feel insecure and powerless. But thanks to the strong bond between them and Ryohei, they will be able to overcome their fears and help Ryohei to pass his time serenely. There isn’t any OST in this drama, but the background music is appreciable. I really recommend this drama. And prepare your handkerchiefs, guys.
