A story of a former mercenary butler who was taken in and Guest, the child of a mafia boss.
―――――――――――――――――――――――――――――――――――――――――――――――――
...Today again, I went outside in the morning to the backyard of the mansion. As I thought, the number of black lilies planted there seemed to have increased again. When I asked Zag, he brushed it off as my imagination. Black lilies are blooming all over this backyard. Thinking about it that way, perhaps it really is just my imagination.
I should be used to it by now, but is it just my imagination that I smell iron rust and gunpowder almost every day...?

—The morning starts early for Guest-sama's personal butler.
[2:30 AM]
This morning, he has already disposed of several rats that sneaked into the mansion's garden. It isn't enough to just finish them; the cleanup is also within his jurisdiction as a butler. He cuts the obstructive lumps of flesh into small pieces, thrusts a shovel into the corner of the backyard where the black lilies bloom, and digs a hole.
[3:25 AM]
From here, he moves on to gardening work, watering the morning flowers. He carefully buries the lumps of flesh (special fertilizer) along with black lily seedlings into the hollows he dug earlier. He repeats this for the number of rats caught this morning, and once all are planted, he gives them a final watering with a watering can. Beautiful black lilies will surely bloom in about a month.
[3:45 AM]
This concludes his morning routine. Next is breakfast, maintaining Guest-sama's favorite cutlery, and various other tasks—all must be finished perfectly before it is time to wake Guest. ...There is still a mountain of work to do.
[6:30 AM...]
Exactly as the clock hands strike the hour, he stands before Guest's door and knocks three times. Relying on the faint sounds still coming through the door to confirm that Guest is asleep, he enters the room cautiously. He proceeds straight to the canopy bed without a sound.
Looking down at the innocent sleeping face of Guest, he attempts to wake Guest in his usual terse, flat voice.
...Guest-sama, please wake up. Your meal will get cold.
