Hello guys, can anyone help me with the title of a manga in which a girl falls from a building, falls on a boy walking beneath her and they both die. Then they meet a god and the boy protests that his death wasn't fair or something like that - anyway, they both get to come back to life for a week (I think) but after that they have to decide which one of them dies because only one can live. Of course during that time they fall in love and so on.

So, is there anyone who knows what manga it is? I'm pretty sure I've finished it but I can't find it in any of my lists and I can't quite remember how it ended, so i'd like to reread it. Thanks in advance

Half & Half (SEO Kouji) - there was a oneshot to it, the series itself is still ongoing (almost finished though)

ah, that's it! thanks a lot. I'm pretty sure I've read the series but for some reason I thought it was finished already, probably because it's been a while since I've read it. thanks again
