Remember, kids: a portal gun in FNF leads to a new dimension. Juki was hanging around and playing with his weapon, while suddenly made a hole in the ground. That’s how Girlfriend and Boyfriend appeared in his world. It was a great event in Juki’s life as he’d been dreaming about a rap battle for days. Finally, they make a deal: if the boy competes with him, Juki sends the couple back home. So there’s no other way to return Girlfriend to her parents except for defeating Juki. Do it quickly or meet the furious Daddy Dearest. It’s your choice.
