My Dad Is an Overprotective CEO

Yan Ci was originally called Yan Yun, and she was the younger sister of Yan Yu, a CEO who doted on his little sister. Then one day, when she was twenty-eight, she was suddenly struck by lightning and turned into a little kid. Yan Ci: Shocking!!! Yan Yu: Come on, call me big brother. Yan Ci (deadpan): Do you want Mom and Dad to lose face in their old age? Yan Yu: Then call me Dad. Yan Ci: ... (Yan Ci doesn't want to talk to you and throws a Yan Yu dog at you.) Meanwhile, the young boy next door was overjoyed. He'd liked this big sister for so long, and had always regretted being born twelve years after her. But now... she'd become so tiny. Could he pat her on the head?
