The little demon Jingjing is a hard-working little demon. The most important tasks are to practice and eat. The things in this world are so delicious, especially the beautiful sister's tears. Some of them taste like sweet-scented osmanthus cake, some of them taste like frost flowers, and some of them are bitter than the herbs boiled by the local mother-in-law. Yabai said that he would stay with Jingjing until Jingjing found her heart.
