Jeon Jungkook, Kim Taehyung. Completely different in many ways but unexpectedly similar in others. To say the least, they're like the Moon and the Sun. One is quiet, smart, calm. The other one is loud, perverted, reckless. On the contrary to their different demeanors, they are both rich, powerful, famous, both heirs to the major companies in South Korea. But.. What if one day, out of the blue, they will have to introduce themselves as husbands? How will their lives go on after that? It was all so unexpected!
