Noah Sandborm

Noah Sandborn is a nineteen-year-old boy with a mysterious past. He moved in with his uncle after a car accident kills his parents. Noah makes friends with Kevin Peterson whose mother, Claire is on bad terms with her husband, Garrett. She is also a teacher at their school. Noah falls in love with her and despite Claire's objections, she lets him seduce her and they end up having a one night stand. The next morning, Claire tells Noah that what they did was a mistake because she was vulnerable and suggests that they stay friends. This angers Noah causing him to snap and punch a wall, alarming Claire. Claire then realizes her mistake when she discovers that Noah is now her student. Even worse, he has developed an obsession with her and become a bad influence on Kevin. Throughout the course of the film, he tries to murder her estranged husband and son by tampering with their vehicle brakes while trying to win over Claire's affections.

Noah is first seen in the film helping Claire lift up the jammed garage door as she tries to pry it open so she could get her son to school. After such help, he then introduced himself as the new next-door neighbor to Claire and her son Kevin whom he immediately befriended. After helping them both, he took Kevin back to the maintenance store to get some fixing supplies so he could fix the garage door. After this, his wheelchair bound uncle tells Claire that Noah lost his parents to some accident years prior to being orphaned. Soon after, Noah helps Kevin get the supplies as well as helping him win over the affection of his crush who works at the same store, a woman named Allie Cambridge. After helping him, three bullies show up and start humiliating Kevin in front of his crush, and Noah takes notice of this, and eyes the bullies after they all leave the store with a pondering stern look in his face for vengeance. After the incident, Noah arrives at Claire's house helping her prep her house when he tells her about the bullies harassing Kevin and Claire confides in Noah that Kevin was stung by a bee when he was child and some bullies took advantage of his weakened state and picked on him and despite Noah's concern, Claire tells him not to worry about it and is overjoyed when the garage door opens, leading her to thank Noah for his help. Later that night, Noah is in his room when Claire watches him from her bedroom window curiously of her new neighbor.

The next day, Noah gains over the trust of Claire and Kevin further by helping with various tasks fixing their house appliances, as he's seen helping Kevin fix the car with tools while Claire looks on heartwarming of his helping and friendly nature. After which, they all have lunch with her friend Vicky who immediately calls him a "strange kid" who likes literature. Noah overhears this and tells Claire that he admires Homer's "Iliad", even giving Claire a literature book as a token of his favor. Claire is touched by this generosity and accepts his gift. After her husband Garrett (whom she's separated from) arrives and takes Kevin for a father-son bonding getaway, Noah watches Claire from his roof and gives her a book of literature then compliments her on her shoes telling her she's doesn't have to try so hard to be "sexy" for she already is beautiful and Claire though surprised, is touched by this and accepts. Later that night, alone in her house, she tries on her heels after a shower and watches Noah from her bedroom window, seeing that he is naked and alone but hesitates and goes on her double date with Vicky which turns out to be a disaster because her date is disrespectful, misogynistic and only cares about money and not literature. After this, Claire leaves her date and goes home.

After this Noah calls Claire on his phone, asking for help about cooking a defrosted chicken in the microwave. Claire laughs at this and Noah asks for her help. She agrees and goes over to his house where she helps him cook the chicken and they have dinner together where she confides to having a disastrous date and Noah unashamedly flirts with her
