Movie about a guy who survives a bus crash

It’s a Japanese movie I saw on Netflix. It began when a guy and his girlfriend got on a bus and it crashed. a couple months after this guy was visiting the sight of the bus crash when he sees this girl who also survived the bus crash. They were the only two survivors. Anyway they hang out a little while when the man tells the girl that his dead girlfriends in heaven. This is when she tells him that there is no heaven and that after the bus crashed when she almost died gave her the power to see hell (point of the movie) after they get back to the apartment they get to know each other they have sex multiple times.

Got something to say?
