Ou Lan's lost look at the thought of her father touched Ou Chenghai, who didn't want to lose this daughter either. So he emotionally wrapped his arm around her shoulder, "Alright, Dad won't overthink it, it's just, Yongjia she..."
Although they had never lived together, and he didn't even know if the daughter who had been a princess from a young age would be willing to acknowledge him, the blood relationship couldn't be changed. He also cared about Baili Yongjia, who was his biological daughter.
He also worried about what would happen to Baili Yongjia if Ou Lan recognized her roots and returned to the family.
