Mara Mabel loves her dad's girlfriend, Mia, for two reasons: she's nice and she's rich. Like, has-a-mansion-for-a-house rich. So obviously, she's excited when she and her dad move in Mia's house. And it goes wonderful for the first couple of hours. Until Mia's son comes home. Dom makes it clear to Mara that he doesn't like her, and so she obviously hates him too.
But the fact is, they have to go to school together, they have classes together, and she's living in the room right next to his. Inevitably, Dom and Mara stop hating each other, and get closer, whether they like it or not. But when Mara starts to grow some feelings, so does a lot of problems.
