Kim Seokjin - JinKook

Seokjin and Jungkook are complete strangers. Seokjin is a renowned alpha, a powerful CEO, but he had an omega who became pregnant. She refused to keep the baby, wanting an abortion and to move on with her life, but Seokjin begged her to have the child, and she did. She gave birth and then abandoned them both to pursue her career abroad. Jungkook was an omega; his alpha cheated on him and broke up with him when he found out. He had his son alone. Both babies were born on the same day, in the same hospital. At some point, Seokjin and Jungkook crossed paths and instantly hated each other. Seokjin was too pretentious for Jungkook, and Jungkook was irresponsible for Seokjin. Jungkook named his pup Minjun, and Seokjin named his Jihoon.
Three weeks after the puppies were born, both were settling in with their supposed parents. But then social services arrived, noticing the serious mistake made at the hospital. The two puppies had been switched, and now they were being forced to be switched again. After that, both suffered a lot of stress; neither puppy stopped crying, overwhelmed by unfamiliar places and smells. They couldn't even adjust to feeding, one adapted to formula and the other to nursing.
