Not the right type of life he wants for his family

When Lilou returned to the mansion, she flinched at the figure leaning against the wall when she closed the door. 

"Goodness!" she patted her chest, looking to her side only to see Samael leaning against the wall, arms crossed. "Since when did you return and what are you doing here leaning behind the door?"

"I didn't return because I never left," he explained and then cocked his head to the side. "Are you alright?"

"Oh..." Lilou pressed her lips into a thin line, giving him a cautious look. She cleared her throat and raised her chin up, mustering her courage to ask him a question.

"Can you... tell me how this regression happened?" 

Samael blinked twice, ever so slowly. "Sure."

"Really?"

"Mhm."

"You will tell me everything?"
