To not let her hand go

At Yang Global Hospital, Country D

Berry immediately rushed to the hospital and stayed by her mother's side while her father was still inside the operating room. He apparently needed an emergency surgery because of his heart problem and was quickly ushered into the surgery theater. 

Berry comforted her mother. Both of them were so worried, and they could only pray and hope for the operation to be a success. They stayed there waiting, praying till the sun went down.

Soon enough, the doctors finally went out of the operating room and informed them that the surgery was a success. Berry and her mother sobbed tears of joy as they hugged each other, thanking the heavens for the miracle they received.

Berry promptly arranged everything in the hospital, shaking her head as she grabbed her mobile phone from inside her purse and saw that it was off. She forgot to charge it, apparently, so the battery was currently empty.
