You Must Fall in Love with Your Mortal Enemy in a Horror Dungeon

The system told me that I must fall in love with my enemies before I can leave the instance. While I stabbed the ghost with my mahogany sword, I shouted to him behind me: "Brother, protect me." He sneered and twisted the monster's neck, pressed me into a pool of blood and whispered: "Pretend to be more... My sister didn't look like this when she kicked me into the abyss last time." Until one day, the system suddenly failed, and all the players witnessed the live broadcast of us embracing each other. And he was biting my earlobe and laughing softly: "Congratulations, the real part of the fake show... Begins now."
