Yes, she initially married into the Xiang Family to pay off her father's debt, and now that the debt is cleared, she came clean and she is leaving clean. The people of the Xiang Family didn't give her too much trouble, and on the contrary, she learned quite a few things. You could say, in this marriage, Zhong Lingling made a huge profit!
So why is she still so heartbroken?
"Don't think that you're really in love with that Xiang Yimo. It's only because I wasn't by your side during that time. You felt helpless in a strange environment and that's why you depended on him. Your dependence on him is temporary, not love! After you come back to E Country with me, you'll soon forget about him!"
Without mentioning Xiang Yimo, Zhong Lingling could hold back. But as soon as Prince Luo Ye brought him up, she couldn't help but start sobbing softly, as heartbroken, helpless, and lost as when she was a child waking up from a nap and couldn't find her mother!
