This drama's title is "Sekaino-owarini-saku-hana" ≒ "The blooming flower when this world is end".
Tidbit (a little introduction);
Saki as Umika and Taiyo as Aoi were waiting for kidney transplant from when they were a child.
Before long, They will fall in faint love.......
Umika-chan costars with Aoi Nakamura in CM of Calpis now. They look good friend. ヽ(^。^)ノ

The drama only air with Japanese Docomo's mobile phone.
Therefore I cannot see this drama. I'm afraid that I didn't use Docomo's terminal now. 。・゚・(ノД`)・゚・。
