It's What You Do to Me (1)

Delilah's life is perfect, isn't it? She's engaged, her stalker has been put in jail, and she's probably now the most popular girl in school. But when two new students show up, her life starts getting mixed up once again. And when Delilah starts to get notes again, she does what she had always done, she keeps it a secret. And when something serious happens with River, she doesn't know what she's supposed to do. But if her stalker is still in jail, who could possibly be sending her notes?
