Their asking price

Lilou rushed to the mansion's garden to meet Tilly and Fabian. She didn't bump into anyone, fortunately. She was a little cautious since she didn't want to see Samael in her current state. 

"Here. There's dirt here." As soon as Lilou reached the garden, Tilly was pointing in a direction. "And there's a grass that isn't cut the same as others."

"Lady Tilly, you're very helpful." As usual, Fabian smiled until his eyes squinted into mere slits. His eyes fell in the direction she was pointing at and over the grass were cut petals. When he raised his eyes to Tilly's hand, she was holding a flower whose petal was the same as that one she was asking him to clean up. 

His lips stretched. "Lady Tilly, don't you want me to finish my task?"

"I am training you," she replied in her usual dull voice. "Fabian don't get annoyed easily."

"That is because no one is purposely trying to annoy me."

"But breathing already makes you annoyed."
