The Beast Won't Let Me Sleep

Adele is a notorious villainess among the high society; rumor has it she married and murdered an old marquis, then allegedly seduced her stepson out of lust for power. As such, she's shunned and ostracized at social gatherings— until she meets the most sought-after man of the era, Count Vyce. However, this man turns out to be Chris, the poor boy she looked after before abandoning him long ago. The once-fragile boy now approaches her without hesitation. Does he approach out of past attraction, or is there something more underneath?
