Hi, so I'm looking for an extremely moving and extra poignant romance manga. It doesn't have to be too romantic as long as it's depressing and it took you days to move on after reading that manga. It doesn't have to be too long or too short as long as the status is complete. Please no ongoing statuses. It can be too tragic, that's okay as long as it's not corny (for you). It doesn't have to be too serious. Smut is tolerable, no hentai or ecchi. I liked Haou Airen, 100% Perfect Girl, i forgot the rest.
Other suggestions (keep in mind that I'm terribly sentimental xD): Chrno Crusade (the romance isn't that noticeable, but it made me cry) Mademoiselle Butterfly (sweet. And I also surprised with it) Taiyou no Uta (the movie is also amazing, I haven't watched the dorama) Rakuen (SAKURAKOUJI Kanoko) (forget about the third oneshot. All the others made me cry. I think the second was even more sentimental, if I remember)
