Intro. Jeon Jungkook is an alpha with lupus, who always had everything he ever wanted, however, when he was 6 years old, he saw his mother come in with a small defenseless and scared girl, apparently scared, and he said he never saw her again, until early in the morning when Jungkook was going to get hidden sweets, he saw the girl trying to get water, he tried to talk to her, but she ran to the attic room, and from there, he went to her door, talking to her and ask her to play with her cars, even without ever getting a response. His parents always worried more about the omega than about him, who was their son. Now as an adult, no longer paying attention to that stupid door, already working and spending his heat period with omegas, his parents went on a trip and ended up having an accident and dying, and as a last request, they told Jungkook not to abandon the omega, and to take care of her like a younger sister, leaving Jungkook furious. What was so special about that omega in the room?
