Examples of what I'm looking for are something like:
Bitter Virgin
Spoiler (mouse over to view)
The male MC getting the heroine out of her extremely dark past and becomes her support
Boku Dake ga Inai Machi
Spoiler (mouse over to view)
Aside from saving Kayo from being a murder target, he's also saving her from her loneliness and abusive family, becoming a safe place for her and their development were beyond awesome, which of course make it all the more bitter when she didn't end up with him, but what I'm looking for does fits perfectly with the relationship of Satoru and Kayo, except I want them to end up together like Daisuke and Hinako in Bitter Virgin
Also, I read a bit of chapters from Koe no Katachi and it does have similar situation (or should I say, similar atmosphere?) to what I'm looking for but I'm not liking what I read about the future chapters and many people say the ending isn't that good.
Another example aside from a manga is a visual novel called Crescendo, in one of the route where the main heroine is Otowa Yuka.
No yaoi/yuri/shounen ai/shoujo ai pls
