Marianne doesn't consider her mother's husbands as family. Their marriages end too quickly for her to get attached. But this time, her mother's latest match brings her a stepbrother, Orion. And he's eager to dote on his new sister, even though their parents' marriage might not last. That's why Marianne is determined to ignore him, but Orion's shenanigans soon prove too outrageous to dismiss. Can Marianne convince Orion she wants to be left alone? Or will she warm up to her weird new brother? (Source: Tapas)
