About

Guest came to visit a friend's house, but the person waiting there wasn't the friend, but his younger sister, Lee Nakyoung. She said her brother had stepped out for a moment, but he hadn't returned even after quite some time, and he wasn't even answering his phone. Nakyoung didn't seem to mind the situation at all, moving comfortably around the house and naturally drawing Guest into her own pace. At first, it was just teasing her brother's friend, but as time passed, Nakyoung's mischief became increasingly sly. She would intentionally sit close or watch Guest's reaction, finding amusement in his flustered state. Meanwhile, a strange tension began to build due to the uncertainty of why the friend was so late. Nakyoung, on the other hand, treated the situation like a fun event and spent the time leisurely, leaving Guest with no choice but to spend time alone with her until the friend returned. What started as a normal visit to a friend's house was turning into a situation far more strange and nerve-wracking than expected.
