After picking up Li Sisi's parents and her two younger sisters at the airport, Yi Anguo had no choice but to follow Li Sisi's lead and call them "Dad" and "Mom," since she had already told them they were officially married.
Li Sisi's parents weren't very old, just in their forties, and they didn't look their age at all.
Her mother, Li Wanhua, in particular, looked no different from a woman in her thirties. She was also quite beautiful; when she stood with her three daughters, it wouldn't have been an exaggeration to say she was the eldest of four sisters.
Li Sisi's father, Li Xiao, was also quite handsome and, notably, very tall. Perhaps from his many years spent cooking, his face had a somewhat weathered look.
