I think the order of PV's should be: Love song > Last Angel > Virgin Road, because it looks like in Love Song she actually has flashbacks what living with her 'hubby' was like (before he died). They used to be happy, until he started cheating on her and when they finally robbed the bank, he was shot and Ayu had to live on, until she too broke down.
Last Angel connects right at the point when she broke down on the streets and shows the suffering she had to go through (internal conflict = Ayu at the parking garage, singing Ayu in the background) until Mannie 'hubby' picked her up to join in the afterlife (Ayu in wedding dress)
The whole story of Love Song and Last Angel (minus the cheating hubby) was already seen in Virgin Road.

The reason I'm thinking Mannie actually died before Love Song even started:
Well for starters Ayu isn't interacting with him when she leaves the apartment.. she just picks up the framed picture and isn't even looking at him. Another indicator would be that the car actually drives through a puddle and the water is splashing out of it, but when Mannie is running through it, nothings happening and the last; he doesn't have a reflection in the shop windows.
So, IMO, he's dead and Ayu tries to live on, until she can't handle it anymore.

Well, my 2 cents ^^;
