About 4-5 years ago I watched a Japanese (I think movie), this is what I remember...

There was a guy who was a small time crook, who would rob places with his friend. He met this girl who was operating an illegal store on the street and they fall in love. Sometime later on they have a huge fight and he leaves, and him and his friend decide to rob this big mansion or something.
They succeed in robbing it but end up caught, and the two of them are tied up and are on their knees in some dark room. The bad guys shoot the main characters friend in the head, and then ask him something, his phone rings (Its the girl) and they shoot him, then the movie ends.

I've been trying to find the name of this movie for years now...
