The Demon King's Best Friend

They say some people develop a baby-bird attachment. When Satara opened his eyes for the first time, the first person he saw was Lucifer. After debating between two names for a while, Lucifer told him, "Your name is Satara. It means Lucifer's contract." Much later, he asked again. The man said, "Once you accept that name, you can't run away." Pairing: Lucifer/Satara (Boye). Happy ending, no angst. Devoted shou (?) and demon king gong. This is an OC story, and basically just an OC in this particular AU. By default, all the characters' settings can be switched around in another AU, including gender, sexuality, species, gong/shou roles, and pairings. Everything that happens is decided by my personal preferences. Theme: Satara, you did great.
