Wolfish CEO's Nightly Delights

Edna had lived with Helmer for four years under the same roof after her mother remarried his father, Helmer becoming her stepbrother. As the CEO of consortium, Helmer was always overbearing, and he found pleasure in toying with Edna. Edna had no choice but to leave, going abroad three years ago.

Helmer punished her for her leaving, and he also fell in love with her for the days they spent together. But when the contract expired, she chose to leave for the second time. Would he let her go?
