The Gangster Itself

11 Girls, 2 boys. It's total is equal to the number of the members of their group, the Black Thirst. With the founder, ChaeRin Luisanna Scott. Half Korean, Half Canadian.
All in all, they're happy, but unexpected things happened. So many revelations. So many confessions. And so many betrayals.
And what if Chaerin's best rival comes in their way? Can the Black Thirst defeat or even fight with the Red Shitters?
Will they be able to surpass all of it? If yes, will they surpass it as a group? Or as an individual former member of their group?
