Probably because Lu Yebai's promise is quite convincing, President Bai and his wife ultimately accepted him as a son-in-law.
Alternatively, they might not have accepted Lu Yebai as a son-in-law, but rather accepted the fact that Bai Cenlin and Lu Yebai have already received a marriage certificate.
After all, things have come to this point, and there's no meaning in further obstruction. Moreover, given Bai Cenlin's current situation, she's already infatuated with Lu Yebai; even if the Bai family tries, they probably wouldn't be able to change her mind one bit.
Thus, President Bai and his wife didn't want to play the villain in breaking up a couple, so the marriage of the Bai family's second daughter became an indisputable fact without any fuss.
Coming out from her parents' room, Bai Cenlin let out a long sigh and directly opened her palm to Lu Yebai, which was covered in sweat...
"Scared me to death."
