Topp Dogg Fanfic- Two Groups, One Heart (completed)

The new male, Korean pop group, Topp Dogg and the new female, Korean pop group, G4 Squared are debuting under the same company. An intentional act done by the company was to have the two groups have relations. Siblings living across from each other in the dorms, protective brothers, scary background stories are all natural for these twenty-one pop idols. The only good thing that happens is the closeness that develops. Love for one another becomes the most important thing to these idols. What will they do once it's taken away from them, though?
