What do you think is that saddest ending of a romantic manga?

*spoilers might be present*

OK I will start.
When I finished reading Absolute Boyfriend, it was sooo sad... I wish it ended differently.:( It was still a good Manga though.

when i finished watching chrono crusade, chrono and rosette sat on a swing chair at a house in the middle of nowhere. they both die at sunset with both holding each other hands.

Mine would have to be from Negima the Anime cause Asuna dies then everyone has their own way of dealing with it save for Negi who later thanks to Yue has a crazy idea of bringing her back(but it wouldn't be the real her only a clone of her)

would basilisk count?
