Are there any stories where the female lead is raped (either at the start of the story or before) and it deals with her trying to have a normal relationship after that horrible event? The male lead helps her through it and she falls for him.

Antique Romance, Asa mo, Hiru mo, Yoru mo. and Bitter Virgin comes to mind...

Eden no Hana (not rape, but sexual abuse though).
Mars (not 100% sure that she was raped though)
