i don't think it's as slow as aozora pedal, but i don't think it's like, as upbeat as "love so sweet" for example. but from what i can hear, i think it sounds different, which is good. once we see the drama, i'm sure we can tell if the song fits it or not.
but omg...the whole day in school i could not get over how HOT ryo looked. and nino! i love his serious face
edit; YAY! found another clip of ryusei no kizuna news:
