Veronica (Ronnie) Miller

Ronnie
Veronica Miller is a rebellious seventeen year old that spends an entire summer with her dad, Steve. She was furious at Steve for leaving the family three years the previous summer. In those three years, Ronnie is accused of shoplifting, and fighting constantly with her younger brother, Jonah and her mother, Kim.

Will Blakelee
 Will Blakelee,  a popular and skilled  beach volleyball player, Will aspires to attend a top university and volunteers at the  Georgia Aquarium. He is Ronnie's love interest.

After arrival, Ronnie becomes miserable, defiant, and defensive toward all those around her, including handsome, popular Will Blakelee ( Liam Hemsworth) whose introduction involved crashing into her during a volleyball match, and accidentally spilling Ronnie's strawberry shake on her. She shrugs him off and meets Blaze, an outcast who lives with her boyfriend Marcus.

Later on, Ronnie discovers a  Loggerhead Sea Turtle nest at the beach by her house and while protecting it, she meets Will again on his volunteer work for the aquarium. After a night of staying up to defend the turtle eggs from predators with Will, she discovers he is deeper than she believed, and begins to develop feelings for him.

As Ronnie falls in love with Will, she also manages to form a better and stronger bond with her father. As their relationship deepens, Will invites her to his sister's wedding. When Ronnie goes to buy a dress for the wedding, she sees Blaze crying over Marcus kicking her out of his car. She approaches Blaze sitting on the road and gives her the money meant for the dress. Her brother ends up giving her money for a dress so she can look nice for Will. At the wedding, Marcus comes and causes a scene with Blaze and Will ends up hitting him after he harasses Blaze and Ronnie. Later that day, the turtle eggs hatch and her father collapses. Ronnie immediately has Steve rushed to a hospital and learns that he has stomach cancer that has spread to his lungs. She decides to start spending more time with her father since he is unlikely to survive much longer. Around the same time, Ronnie and Will get into an argument after Will confesses that Scott, his best friend, had actually set fire to the church. She is outraged that he let everyone believe that her father was the culprit. With Will soon leaving for college, there is no time to patch things up.

At her father's funeral, she stands to make a speech but declares that no words would ever be able to show how wonderful her father really was. Instead, she decides to share with them the song she helped finish. Before she sits down to play, sunlight shines through the stained glass window. Ronnie smiles and says "Hi, Daddy." remembering what she overheard her father tell Jonah earlier in the movie; that whenever light shines through the window, it's him.

Blaze and other townsfolk offer Ronnie sympathy and kind words after the funeral outside. Later on, while talking to the attendants, she runs into Will. He says that he liked the song she played and that he knows her dad did too and Ronnie thanks him for coming. Having decided to attend Juilliard, Ronnie is packing up to return to New York when she sees Will standing outside. She goes outside to see him and Will apologizes to her for everything that had happened and Ronnie forgives him. Will surprises Ronnie by revealing that he will be transferring to Columbia in order to be with her and they kiss.
