Can’t remember the name of a movie and I only have memory of several scenes

A few key points/scenes :
– Man kissed woman (in Mexico or Hawaii I forgot) and they shared their own background afterwards but man was reluctant to disclose true details
– At a bar/restaurant, woman went to washroom and man found out a book in which she wrote something about him. This made him mad and he left the bar
– Man taught something at kindergarten as a volunteer
– Man has a younger brother
– Near the end of the movie, woman invited man to join her basking on the street
– Last scene by the river
– The actor who casted the man was quite tall
– As I remember the woman was called Emily (not 100% sure) in the movie

Thank you
