Ps: If you want to see Miss Under the Brocade's kiss, you can go to Weibo and go to my Weibo to see it. Weibo name: Cat with Broken Wings 2011, and edited the same series "Under the Brocade 2". It's sweet and sad. Fortunately, after going through many twists and turns, Yixia finally succeeded in holding hands. It's not easy.
Purpose: To express Xia's happy married life
