Meng Yaozu was the name of Meng Renshu's father and also Li Caiyi's former father-in-law.
He was a man with fiery ambition, like Li Jirong. However, unlike her father, who did not care about family, Meng Yaozu was better in that area. Even towards the daughter-in-law, whom everyone thought as useless, Meng Yaozu never treated her discriminately. On the contrary, he defended Li Caiyi a lot in front of his wife and his biological daughter.
Li Caiyi had always felt thankful for this man and long considered him as her second father. She always heeded his advice to be more patient with her mother-in-law and sister-in-law. She also never doubted his intention.
Among many figures in high-class society, Meng Yaozu and Meng Renshu were the only ones she could depend on. However, since Meng Renshu often went away on business trips, Li Caiyi became more reliant on Meng Yaozu.
