Ah, you're too lucky! You came to the perfect person for help. Luckily there are two manga that I finished, which I loved a lot. And one anime to suit your desires.
Manga:
1. Watashi no Messiah-sama (My favourite manga to the highest degree. Made me cry, smile, weep like a girl who was just dumped, sometimes laugh like an idiot. Overall it is too awing, especially the romantic developments, twists and shocks in this manga are really great!)
2. Shina Dark
3. Mirai Nikki (Though I haven't read it, there is a high probability that you will fall in love with it. There is a one-episode anime of it too, so get over with the manga!)
Anime:
Ichiban Ushiro no Daimaou (This is the only one I can think of at the moment, will tell you of any other if I remember any.)
Other Manga that you may like:
Mx0
Aflame Inferno
