After Mistakenly Marking My Ex’s Big Sister

Ye Zhiqing is a traditional alpha who, after three years with Yu Xi, only held hands. When she proposed, Yu Xi broke up with her, finding Ye Zhiqing too old-fashioned and her pheromones too weak to satisfy her. Determined to win Yu Xi back, Ye Zhiqing took a powerful supplement that overloaded her pheromones. On the way to Yu Xi, she accidentally spends the night with an omega in heat—Yu Li, Yu Xi’s formidable elder sister.

Yu Li, who suffers from pheromone disorder, finds Ye Zhiqing’s pheromones could soothe her, easing her headaches and insomnia. After realizing this, she decides to forcefully marry Ye Zhiqing.

Meanwhile, Yu Xi regrets the breakup and tries to reconcile with Ye Zhiqing, only to find her in a loving relationship with Yu Li.
