Think western fairy tail meets ecchi love triangle story and you get Pajama na Kanojo.

A story about a girl who falls into a coma but her spirit is still visible to her childhood friend, who in the mean time is trying to find away to bring her back into the world. Whilst he tries, he keeps running into a series of misunderstandings with the most beautiful girl in his school.

The artwork for the manga is very typical with romances, especially with ecchi romances - so expect a lot of graphic drawings. The disappointment so far have been the characters which don't come across as likeable, thus contributing to lesser enjoyment of the series which already exists from this being a sad story.

Something like this does seem to be something Weekly Shonen Jump would run, but whether it gains popularity is yet to be seen.
