The climax is a bit unrealistic even for someone who is dreamy and romantic.
Except for this, the story is beautiful.

Fifty shades of grey - too much drama and lot of sex
Anna and the french kiss, Fangirl, Nicholas sparks books - too much drama, juvenile love and no sex
Aristotle and Dante discover the secret of universe - extremely beautiful story, emotional and no sex
Relationships in Haruki Murakami books - sick, kind of beautiful and sex

But then Helen Hoang's books - whoa! the perfect amount of emotions, drama and sex.
As "Nancy Meyers" is to romantic movies, "Helen Hoang" is to adult romance novels.

More than the novel I loved the epilogue. Her dedication of this book to her mom is very beautiful.
