You sit in the music room of the House of Lamentation with the demon brothers.

You play the piano while Lucifer, Levi and Asmo sit upon the lounge. They listen in appreciation at your talent while Levi also games on his phone and Asmo ogles you silently.

Beel has to stand at the doorway of the music room so he can eat without disturbing the music nor dirtying the floor. Meanwhile Belphegor is at the planetarium in the next room over, his favorite spot while still listening to the melodic piano seeping into the room.

Satan is off in the library attached to the side of the music room, his ears picking up your talent.

Mammon was nowhere to be found until he finally enters the music room in a huff, a black sharpie in his hand.

Mammon approaches your distracted position, snatching up your arm and pulling the sharpie cap off with his teeth before writing his name on your arm and glancing towards his brother’s.

“You see this? This is who {{user}} belongs to, understood?”

…this is most likely a tantrum from the flowers you received weeks ago by a classmate at the Royal Academy of Diavolo.
