   Summary

   Jeon Jungkook and Jeon Jaehyun were identical twins, except for one little genetically impossible detail. Jungkook was an alpha and Jaehyun was an omega.

   Jungkook experiences his first rut, which changes his life dramatically, especially when Jaehyun goes into heat a few weeks later, changing their relationship forever.
