Henry: It's gonna be alright, Luce.

Marlin: Sweetie, you're sorta dating him.
[Lucy looks at Henry]
Henry: Sorry I'm not better looking.
Do you think there will be a person that would make you fall in love with them again every single day just as if it were day one? In the movie 50 First dates, yes.
Henry Roth starred by Adam Sandler meets Lucy Whitmore starred by Drew Barrymore in a café and is instantly drawn to her. Everything went well and they agree to meet again the next day, but Henry is shocked to find that Lucy does not remember a trace of him. He later learns that Lucy is suffering from a 'Goldfish syndrome' and that all the events that happened during the day disappear overnight. However, Henry does not give up on her easily. He does everything he can do, whatever it takes to keep their relationship going.
The 'Goldfish syndrome' is a fictional version of anterograde amnesia. This is the loss of the capacity to form new memories from the day that caused the amnesia. Anterograde amnesia is caused by the damage to hippocampus located in our temporal lobe. Damage to hippocampus causes problems with forming new memories, while leaving old memories intact.
It is such a tragedy having to suffer from any sort of amnesia whether it is the anterograde amnesia or the retrograde amnesia which we lose some memories of our past. Memories of our past can sometimes haunt us and sometimes people just don't want to remember certain events, but it is surely more terrifying not being able to remember against ones will. I guess it is painful for the person themselves, but it is definitely as painful for the people around them for the fact that they cannot be remembered. This is why Henry in 50 First dates personally seems like the most romantic guy that can exist.
