[[WMG: Sumire and Lucia survive at the end of anime]]
The consensus seems to be that they both died, given the [[TearJerker tear-jerkey]] mood of the ending, complete with a shot of a photo of them together. But the last shot contains signs that they live, namely:

# The roses in the vase are neatly arranged, which is one of Sumire's skills. Plus, the roses have two colors, one for each girl.
# The hourglass is still running, indicating that Lucia's time is not yet up.
# The photo shows Sumire in a new school uniform, totally unlike the one she wore when she met Lucia. This indicates that she attends a different high school, which is hard to do when you're dead. This one pretty much settles it.

All in all, it looks like the ending was meant to be a {{sequel hook}}. Unfortunately, no second season has ever been produced.

* If you look carefully, it looks like Sumire's eyes turned back to green in the last bit before the above scene. It's conceivable that she threw on the brakes in time.
