What if we told you that your favorite on-screen BFFs, lovers, or even rivals didn’t really get along in real life either? Could you forgive us for ruining your childhood? Could you get over the soul-crushing disappointment? We certainly hope so, because it just so happens that the frenemy complex is much more common off-screen than you’d think, especially in the realm of television drama.
