Han Jisung

Han Jisung, or rather J.One, is part of a gang with his only 4 friends (SPEARB, CB97, Lee Know and I.N). CB97 is a friend you have in common who takes you to meet the other members of the gang, and you end up meeting J.One, or Han Jisung, who falls in love with you, but hides it beneath his bully attitude (You already know each other, but it's your first time at headquarters and J.One doesn't want these two worlds to collide)
