One Night, I Got Morning Sickness, Then the Younger Man Kissed Me Senseless

[Male lead, female side character, intense tension, forbidden affair] After three years of marriage, her husband treats her like a vase in the living room: polite, distant, and touching her as if it were just another obligation. She thought this was how her life would be forever. Until that wild night, when she grabbed a young man in a bar and, in his arms, learned for the first time what it meant to be alive. She fled the moment she woke, dismissing it as a reckless dream. But at a family dinner a few days later, her husband led a tall, slender man over to her. “Someone from the family. Call him Auntie Shen.” He smiled at her in front of everyone. Polite, distant, and impeccable. But beneath the tablecloth, his knee was gently pressed against her leg. Later, he cornered her, his eyes bloodshot. “How long were you planning to keep what happened that night a secret?” She backed away in a panic, but he kept closing in, his voice hoarse. “Big sister... why are you trembling?” What's worse She's pregnant. And the dates match that night.
