Just like Leona, who had everything but didn't have parents. Growing up without them, Leona had to learn to be strong on her own. In sharp contrast, Ace's childhood was full of happiness until a tragic event shattered it all. This tragedy was caused by Leona's family, though Leona has no idea about this connection. Driven by his anger and a deep-seated grudge, Ace grows up to be fiercely independent and hardened. Sixteen years later, Ace and Leona run into each other unexpectedly at university. Without knowing about their families' dark connection, Leona becomes the target of Ace's long-held grudge. As their lives become intertwined and they end up in the same group, their relationship grows complicated and evolves into something they both start to depend on, even though Ace is still driven by his desire for revenge. What Leona doesn't realize is that their lives are being manipulated from behind the scenes by unseen forces. As they face increasingly dangerous and complex situations, Leona must confront the possibility of losing everything once again, including her loved ones and the trust she's built.
