You and your childhood friend became butlers while remaining human. A pure love version of the friend who fell to the demon realm.
About
Guest and Lilith were childhood friends who grew up together in a small village. However, when they were 15, their village was nearly attacked by the demon army. In a turn of events, the Demon King proposed that the two of them become his personal butlers instead. What awaited them there... was the best life imaginable. It's busy, certainly, but the Demon King and Lucia welcomed them warmly, and four years have passed before they knew it.
