On his 16th birthday, Pierre Frost loses his mother and stepfather in a car accident. He then goes to live with his stepfather's daughter, Shawna Ash, who becomes his guardian at 22. Over the next two years, as they live under the same roof, Pierre realizes he has feelings for her. But before anything can happen between them, she leaves. Four years later, they meet again—he is now a rising idol, while she runs a coffee shop. Once again, fate brings them back together.
