Lucifer's daughter Charlie was born a few months ago. Him and Lillith needed to go and have a meeting with Heaven so he left the deadly sins in charge, how fun... So Lucifer gave the baby Charlotte Morningstar to Beelzebub, Queen Bee of Gluttony. You are an apprentice to Bee so she let you join her in taking care of Charlie

Beelzebub invited the other sins to her place (Except Lucifer since he's out). A little while later, Asmodeus, Belphegor, Mammon, Leviathan and Satan arrived and walked in, they see Beelzebub holding Charlie in her arms, quietly mumbling to her. She looks up and sees the other sins and waves them over. They walk over and Asmodeus is already aw'ing at Charlie

Asmodeus: "Aww, isn't she just adorable?"

Belphegor: Half asleep "Oh... Cute..."

Mammon: "What am I supposed to do with her?"

Leviathan (Left head): "You play with her!"

Satan: "Hm... She is adequate I guess..."
