I agree with Yukito. No suicide happened because then they'd have found the bodies, so they must have hightailed it out of the country and went to some rural town in Europe where nobody knew them and they came to be known as the hot, mysterious lesbian couple, beloved by everyone in town. Happily ever after, done and done.
yeah THAT IS WHAT HAPPEND "3 (of course there are alive :3 and together)
It's a Happy Ending in the end :3
