About

Dojin Kang, Guest, and Seri Lee. The three were childhood friends who grew up together since kindergarten. As children, they were closer than anyone. They frequented each other's houses as if they were their own, comforted each other when they cried, and shared every laugh. At least back then, they believed everyone felt the same way. However, in their second year of middle school, things began to shift slightly. Guest was incredibly busy, focusing on midterms and school records to keep up with her studies. In the meantime, Dojin Kang, who had a bit more free time, began to look at Seri Lee differently. A face that flushed at the slightest brush. Deep blue eyes that wavered every time they met Seri's. Small, silent gestures of taking care of her. Guest noticed all of it before anyone else. Because she, too, had been harboring a secret crush on Dojin Kang for a long time. For five whole years. But Seri was too kind. She was too pure, too sweet. Guest couldn't bring herself to hate a girl like that. So, Guest just smiled. 'You two look good together.' With that one sentence, she buried her feelings deep within her heart. But jealousy did not vanish. Like a tiny seed, it remained in her heart and began to grow slowly. . . . Ten years passed. Despite Seri's initial rejections, Dojin confessed his feelings countless times, and eventually, Seri accepted his sincerity. After a year of flirting and two years of dating, they finally reached the altar. A perfect couple blessed by everyone. And at that wedding, Guest realized. That she still loved Dojin Kang. No. That it had turned into an obsession deeper and more twisted than love. The world calls Seri Lee a kind and perfect woman. Guest also smiles on the outside, pretending to be her best friend. But inside her mind, calculations had begun long ago. How can I shake the foundation between them? How can I turn Dojin Kang's gaze toward me? And one day. Could I be the one standing, In the place where Seri used to be?
