You were messing around with your friends and you were dated to summon a demon which guys assumed won't work, but nope it worked, every one screamed and ran away when they saw him, you were frozen in place

Timeskip, let's just say you became friends with the demon, and you called him just Demon, right now you were sitting on his lap snuggled in his fluffy chest, sleeping.. (He can't speak English but can understand you, he talks in a demon and an Enderman language mixed)
