DISCLAIMER: This story is set in the universe of Obey Me, a mobile otome game. Specifically, the Realm of Demons known as the Devildom (or Hell for simplicity). The only character in this story that is NOT from that game is Kai, who is taking the place of MC, or the Main Character .

It all started on October 31st, a date Kai would never forget. Up in the Human Realm, it was just known as Halloween. A time to dress up and have fun with friends. But down here in the Devildom, it was Lord Diavolo's birthday. A special occasion, considering that Lord Diavolo is the Crowned Prince and Future King. But to Kai, he was simply Diavolo, a man they had to pretend to like. But they weren't dense. Kai could see the way the Demon Prince behaved in their presence, they knew how he felt about them.

However, there was another. Lucifer, the Avatar of Pride and Eldest of the Seven Demon Brothers. Also known as Diavolo's loyal right-hand man. Over the course of the earlier Exchange Program between the three realms, Kai had come to be close to all Seven Demon Brothers due to living in the House of Lamentation. The 'dorms' where all RAD Student Council members lived. But they felt a particularly strong attraction and connection with Lucifer. A part of them felt bad, knowing that one day they'd have to reject all of them and Diavolo in favor of Lucifer. But the other part felt no pity, believing that they should've acknowledged their lack of reciprocation sooner.

Little did they know just how difficult it would turn out to be. October 31st, Diavolo chose to hold an extravagant birthday party at the Demon Lord's Castle and invited many people. Including the members of the House of Lamentation. As the date approached, a sense of dread and unease filled the pit in Kai's stomach. They couldn't understand why, it was just a birthday party. Why would they have to feel so nervous? But eventually, they found out at the party..

The party started off as normal, until Barbatos requested to speak with them alone. Barbatos was an unusual demon, he had a kind and delicate look to him, yet he was possibly the most powerful demon in all of the Devildom due to his abilities that affected both past and future. And he just so happened to serve as Diavolo's loyal and impeccable butler. The reason Kai found Barbatos requesting to speak to them was because the butler rarely ever spoke to them. And he had made his opinion of them quite clear. Openly stating that he personally couldn't see what the others saw in Kai.

But what was most unusual, was the message that Barbatos had for Kai. "Lord Diavolo is going to have a special speech tonight," he explained, "so don't say anything that may hurt or upset him, understood?" Barbatos said. Despite the smile on his lips, there wasn't an ounce of kindness in those typically gentle eyes. Without waiting for a response, Barbatos walked away, possibly to go attend to Diavolo or serve guests, leaving Kai alone in their confusion. What could he mean by that?

Soon, the time for the speech came, though. Everyone gathered around Diavolo as they waited. But Kai noticed the look of confusion on Lucifer's face. Did he not know about this speech? Was it a spur of the moment thing that Diavolo only kept between himself and Barbatos? Or had Barbatos foreseen it using his abilities? Whatever it was, Kai still found it strange. That familiar uneasy feeling began to settle once more when Diavolo started speaking.

He went on about the usual things, thanking people for attending, making a joke about not remembering his own age, mentioning how he enjoyed sharing his birthday for other important events, until– Kai noticed his gaze had fallen on them.

"Kai, I have something I'd like to confess," he began. Murmurs erupted in hushed whispers from the crowd, what could Lord Diavolo want with the human of all people? "Ever since the exchange program, you've become an important part of the Devildom. And especially in the lives of some gathered here today." Kai noticed the bashful looks on some of the faces of the brothers, as well as the warm smiles the guys from Purgatory Hall wore. "However, out of all those here, I'd say you've also become an important part of my life." Kai stared in confusion, he wasn't saying what they thought he was saying.. ..right?

Diavolo took a deep breath before he continued, "I have come to develop deep feelings for you, Kai. And.. I'd like to know if you feel the same way." The Demon Prince stared at Kai, patiently awaiting their answer. But Kai could only stare back in shock, unsure of how to respond. They wanted to reject him, they didn't want to lie to him. But he was the future King of Demons! How can anyone just flat out say 'no,' especially at such a large social event such as this? But then, they remembered Barbatos' words, and the dread settled deeper.

Kai stared up at Diavolo, regaining their confidence and taking a deep breath. "I.."
