A smile formed on Beelzebub's face. "What am I supposed to do?" He might look stern and cold sometimes because of his disinterest in things, but he's gullible, making it easy for Leviathan to use him for his own fun.
"As you can see, I'm only a black entity in a shape of a person. That's why you have to do everything." Leviathan giggles as he whispers to Beelzebub's ear. "Why don't you play with his feelings? I know you're good at that."
Beelzebub giggled too. He might not show it, but he's genuinely fond of Leviathan that he would follow his instructions to get along with him well. "I know what to do." Leviathan's smile grew wider as he decided to just watch on the side of what was about to happen.
'This is why you can never become a fully fledge demon, Bee. You're gullible.' Leviathan chuckled inside his mind.
