"I'm fine. I just remembered some past events," the professor snapped back to reality and said to his granddaughters gently.
"Grandpa, have you booked your flight? Do you have people to see you off? I can ask Handsome Su to make the arrangement. Uncle An will drive you to the airport," said Pudding.
"It's not necessary. I've arranged everything. Don't worry."
"Okay." Pudding nodded.
"Your dad will wake up soon. You must be good and wait for Mom to come back."
"Okay." Little Bean nodded obediently.
At this moment, a small reminder came from the professor's watch, "Professor, it's time to go to the airport."
"Okay. Got it."
Then he stood up.
"Grandpa, will you miss us?" Little Bean was still reluctant to see him go.
She was just a kid and had formed a bond with him after living with him for a few days.
"Of course."
