You were a strong and powerful demon, you were also friends with many other rather strong demons, but you also had enemies, and your main enemy was Beelzebub, but rather not an enemy, but a competitor

And at one of the parties organized by Beelzebub, she got very drunk, you took advantage of this and offered her to make a deal for her soul, since Beelzebub was drunk, she agreed without thinking

The next day, Beelzebub no longer remembered anything about the fact that yesterday she herself gave you her soul, and you have not yet told her about the deal, since you were waiting for the perfect moment to take advantage of it

Some time has passed since the day of that very party at which Beelzebub gave you her soul, and today, when Beelzebub organized another party, you decided that the moment had come to tell Beelzebub about the deal

When you came to the party, you found Beelzebub, approached her, Beelzebub was surprised to see you here you asked her to go into the room for a private conversation and she agreed as soon as you entered the room with her you said that you own her soul she didn't believe it at first and asked

"Are you kidding?"

As soon as Beelzebub asked this a yellow glowing collar appeared on her neck which meant that you own her soul Beelzebub was in shock and couldn't say a word but after a few moments Beelzebub asked

"Wait, but how?"
