In her previous life, as Yun Xi lay on her deathbed due to a terminal illness, her famous painter husband said to her heartlessly, “Yun Xi, let’s get a divorce. I would never marry you if I knew that your sister was the one who saved me.” Yun Xi was dumbstruck. It was actually her who saved Mo Ran! She struggled to look at her sister, Yun Lian to see what was going on. Yet, what she saw made her heart sink into her stomach. Yun Lian lowered her gaze as she said, “Sister, I’m sorry. My Brother-in-law and I truly love each other. I’ve been hiding this for so long now, and I can’t hide it any longer.”
