What, like a boy trying to impress a girl by getting into the best paramilitary org in the world, failing, returning home a failure, hiding his face so as not to admit his shame while the girl waits for him to return believing he could and has made it as a hero, their town burning down, him spending four years in a tube and one on the run before she now working for an ecoterror group finds him but he is now suffering from MPD and other issues and eventually becomes a vegetable only for her to devote her last days on earth to caring for him leading to her restoring his mind and learning of his love for her as he learns of her love for him, the two of them spending their possible last night on earth intimate together, only to prove successful and alive at the end, so he asks her to be by his side as he starts his new life and they start a family and raise two kids together?
Something like that, perhaps?
