One time this guy decided to ignore everything that he wanted, and to only think of this one girl. From that moment on, everything he did and said and even thought was in her best interest - or at least what he perceived to be in her best interest. He didn't matter at all, even to himself. She was the only one that mattered.
Then, several years later, the guy died alone and unloved.
The moral of this story is that there is no moral.
