[Question] Need diseased Manga!!

[PakTigers]

Listen up, I'm sorry to disturb ya guyz. But I wanna read a manga in which whether the main guy or the girl (protagonist) are suffering from some disease. :scorps:
The genres it might belong: (Highly) Romantic, school life, tragic, sad, tearing, NO ACTION....!!

So please recommend me one, minna!! :T_T:
