Choi Haeseong; a professional dancer at a small dance studio in Seoul Korea, suddenly gets scouted out by a manager from BigHit Entertainment. Haeseong has no idea that Bang-pd will transition him to an already existing group, and neither do the members of said group. As you follow Haeseong you'll begin to realize that some people aren't as nice as they seem. But one out of all of them shows him extra sympathy. Which, you may think is just him being nice. But Jeon Jungkook's feelings go way deeper than that.
