A Butler's Private Lesson - Devilgram
"Happily ever after, it is!"
In the prince's castle, MC is welcomed by Asmodeus, who's curious if MC has made any moves to capture the prince's heart yet. Barbatos assists MC during the ball, and asks them for a dance. As they dance, Barbatos expresses how pleased he is at MC's performance, and is charmed by MC's talents and grace. He confirms that MC captured his heart, and asks them to marry him, as he was the prince from the beginning. Barbatos figured out the plot early on from Satan's behavior. Since they reached the happy ending, MC and Barbatos leave the book just in time for Diavolo's return. Barbatos goes to prepare refreshments, and considers the adventure an interesting story to tell over the tea.
