Sue them

"Yeye?"

Han Zixin opened the door to find his grandfather watching some cartoon series on the television as usual. His grandfather had been living his life the way he always wanted to. When Han Zixin was in university, his grandfather would go abroad for a few months each year. 

Han Qian would spend his time with his eldest grandson and travel on his own. But when it was his younger grandson's holiday time, he would go to him. When Han Zixin got a job, he began staying with his grandson because he decided that he needed stability. However, it was not possible. Han Zixin got more transfers than anything. 

"You brought me a cake, "His grandfather narrowed his eyes at him. "You are getting transferred again, aren't you?"

Each time, he would begin adapting to a place, his grandson would come with a cake to appease him and throw the bomb on him that they were moving. He was too familiar with the younger one's way of life.
