I think so too! Pretty touching drama...
And I like all 3 main casts (i.e. Dohmoto Tsuyoshi, Dohmoto Koichi and Okina Megumi)!
<<SPOILER ALERT!!!>>
But I actually had hoped for a sad ending (a bit sadist, right?),
where Koichi remains unconscious... but the producers extended the ending a bit too much, making it a happy ending...
