Charlie and Nadia (portrayed by Oliver Davis and Aften Opal) suddenly find themselves as step-siblings due to their parents' recent union. What their parents remain oblivious to, however, is that Charlie and Nadia once shared a romantic bond. They've kept their past entanglement under wraps, not wanting their previous romance to jeopardize their parents' newfound happiness... Yet, after sharing a living space, they can't resist the old magnetic pull of their previous attraction, tempting them back towards each other, despite their best efforts to suppress such feelings. Determined, they decide to try their best to not view each other in that light. After all, their parents' relationship is their top priority. Who are they to potentially disrupt it? They can surely exercise self-control... or can they? It's not long before they understand that no matter how much they try to overlook each other... the allure is simply too powerful. They need to devise a strategy to subdue their desires- without alerting their parents, naturally. One day, in the absence of their parents, they devise a scheme. They never consummated their relationship while they were together, so perhaps they NEED to do so NOW, to finally rid themselves of their lingering feelings. It could be their only chance to lead a regular life together. A bite of the forbidden apple before they uproot the entire tree. But will this single episode of passion quench their desires, or will it merely stoke the fire?
