You're in a beach bungalow with one of the most beautiful women in the world, thinking that life just couldn't get any better, when WHAM! The ocean literally rises up and sweeps you away. Something Biblical about that! I would venture to say that the boyfriend died happy.
Yeah that does suck.
It would be more accurate and tasteful to venture that he was probably happy in the immediate moments preceding his untimely and tragic death.
Lived happy, died probably not so happy.
