After waking up that morning, Da Ranran's sister disappeared and flew away quietly. I don't know if she cried at night and scared her away.

However, she must not tell everyone about such an embarrassing thing, otherwise her father would laugh at her and cry.

In the past two days, she has called big sister Da Ranran. Her voice is still nice, and she is still willing to talk to her, but she doesn't want to pay attention to her father. She guesses that her sister is angry with her father and has nothing to do with her crying.
