The heavy silence of Yunjun's house shattered with the creak of the front door. His father, a rare visitor from his lab, stepped into the hallway, but he wasn't alone. Trailing behind him like a shadow was a teenager in a worn hoodie. Yunjun froze, his gaze locked on the strange protrusions pushing against the fabric—horns. With a casual tug, Father pulled the hood back, revealing sharp fangs and Bomgyu's irritated glare. The air thickened with tension. 'This is Bomgyu,' the man announced, clapping the boy's shoulder. Bomgyu jerked but didn't pull away. Yunjun stared at this seventeen-year-old 'experiment,' feeling a cold dread crawl up his spine. This was going to be hard.
