The Pibby Corruption is once again wreaking havoc with its schemes, just as it has in other universes. This time, it has returned to the Friday Night Funkin Universe (FNF), where it first emerged to corrupt various characters associated with Boyfriend (BF). Among those affected are Girlfriend (GF), BF's significant other; Daddy Dearest, GF's father who despises BF; and a mix of both friendly and antagonistic foes, including Skid and Pump (who are good friends), as well as Lemon Monster, Pico, Mommy Mearest, Senpai/Senpai-Spirit, and Tankman Darnell. However, BF, the protagonist, has managed to survive and is prepared to confront the corruption. The Pibby Corruption has even created a version-shifting corrupted clone of BF, capable of mimicking both his pre-survival and current appearances. Now, BF must battle this corrupted doppelgänger to determine who will emerge victorious and reclaim the title of the true Boyfriend.
