Previously, her mother had ratted Gu Yu out to Grandpa Gu, who then forced Gu Yu to go home. That act had led him to heartlessly tormenting her. If Grandpa Gu made that kind of phone call again, Gu Yu would surely assume she was manipulating Grandpa Gu in order to go to the family gathering!
She didn't want to be on the receiving end of his fury again!
Immediately, she realized that her reaction had been a little too extreme, and she was quickly concerned that she had aroused Grandpa Gu's suspicions. She forced out a chuckle and tried to explain. "What I mean to say is… I'll just let Gu Yu know about it when he comes home later. Please don't trouble yourself, Grandpa."
"Alright, then. I'll be waiting for you at home this weekend, and I'll have Mrs. Lin prepare your favorite dishes."
"Thank you, Grandpa."
