Yan Yulan was rescued by a woman and sent to Qishan.
Everything here was wonderful, except that the woman wasn't there.
Yan Yulan couldn't understand why she couldn't stop thinking about a woman. Even being her savior shouldn't be enough to make her feel this way.
Bai Ci also realized that she was growing more and more attached to a little girl.
Yan Yulan worked hard and was always getting hurt. That way, the woman would come to see her.
As Yan Yulan hoped, Bai Ci grew more and more concerned for the girl. She even wondered whether sending her to Qishan had been a mistake.
Yan Yulan never forgot who she was or the truth she had been searching for all along.
But Bai Ci gradually forgot...
Once, Yan Yulan lay against Bai Ci's shoulder, reaching out her little hand to shield her from the rain and wipe her face.
Now, Lanlan was holding an umbrella for Sister A Ci, leaning against her more closely than ever.
Bai Ci had once been wary and afraid, too.
But now she could boldly walk into the misty rain, because the person holding the umbrella was by her side.
P.S. They are nine years apart in age.
Premise: Face the future bravely and keep moving forward with resolve.
