To prevent any disruption, Linus devises a plan to woo Sabrina himself and steer her away from David. However, as Linus spends more time with Sabrina, he starts to contend with unexpected emotions, leading to a clash between his duty to the family business and his newfound feelings. The resulting dynamics among Sabrina, David, and Linus set the stage for significant personal revelations and decisions.
