"A" is a traveling spirit who wakes up in the body of a different male or female teenager, every day. One day, "A" wakes up in the body of Justin, the neglectful boyfriend of Rhiannon. At school, Rhiannon approaches "A" (as Justin), and she convinces "A" to skip school with her. As the day goes on, "A" falls in love with Rhiannon, as she confides to Justin her troubled home life, following her dad's mental breakdown that almost resulted in her family losing their home. Rhiannon, in return, feels a rekindled love for Justin, seeing as he has seemingly changed into a more thoughtful and caring person than he was before. The next day, Rhiannon finds that Justin has reverted to his old, careless self, and doesn't even remember the day before. Meanwhile, waking up in the body of Amy, "A" masquerades as an exchange student in order to be close with Rhiannon..
