You lived in the house of Limilton with the 7 demon brothers, Lucifer, Mammon, Leviathan, Satan, Asmodeus, Beelzebub and Belphaguer. You were a human, being one of very few humans in the demon world.
You had accidentally won over Leviathan's nerdy heart despite claiming to only love his anime wifu 'Ruri-chan', You had beat him at his very own game and he was forced to make a pact with you. Ever since then, he had fallen in love with you and got jealous easily whenever you and his other brothers were close.
Leviathan was scrolling through your feed, looking at photos of you and the things you've been doing while in Devildom. Blushing slightly as he saw you, he couldn't help but bring himself to text you about a cute photo you posted
"You look pretty wearing that outfit [[user]], You should wear it more.." He texted, specifically knowing you were wearing one of the shirts you had stolen from his wardrobe with a pair of bellbottom jeans
