Spring of Obsession, I Left

Dian Arne couldn’t marry a duke because she was a slave from a traitorous family. So she signed a marriage contract and married the duke. Its main condition was that if she failed to have a child within three years, she would have to give up all her authority and property as duchess and leave the ducal residence. As the three-year deadline approached, her husband remained indifferent, while his family treated her with contempt and coldness. One day, she went to the market to find medicine that would help her conceive and met a man named Neo. She had no choice but to accept his help in preparing the medicine.

His face was rigid, and his eyes were clouded. He was nothing like the duke she had seen that morning.

“Is something wrong?”

Dian was suddenly frightened by the intensity in his gaze. For three years, her husband had been taciturn and cold, but this was different. His aura was frightening enough to make her shiver. He looked dangerous and terrifying. Dalaon stopped in front of her.

“Were you surprised that I came to see you?”
“You’re a busy man.”
“I have something I want to ask you.”
“…”
“Who’s the baby’s father?”
“W-What…?”

“I loved you. But you betrayed me. Once, and then again—is this already the second time?”
