Nobody can hear me but you is a story of a timid girl who found a friendship through an invisible cellphone which can surpass even time space and how she move on with it as a tragic accident occurs. See Aihara Ryo's Transition, from a timid girl to a Head Strong girl throughout the story. If you're into drama, then this manga is worth to read.

For me, the art isn't that good (well not too detailed in some parts) but since the story is well written and well-paced as well as the character built was constructed very well, it overshadowed the deficiency in the art part so all in all it was a good manga.
