This question, indeed, he had no good rebuttal for.
But as a man, he is obliged to contribute to the Lu Family, but Xinbai is a girl, she doesn't need to, nor does she have to endure this grievance.
He believes that it's enough for him alone to feel 'aggrieved' for the Lu Family, there's no need for his sister to sacrifice like this.
Therefore, he has always opposed his sister's marriage in the past few years, and Bai Cenlin is very well aware of this.
But after all, their stances are exactly opposite, so they've never agreed on this matter: "I understand, you're the brother, it's inevitable for you to feel heartache seeing your sister aggrieved, but I'm also the elder sister, seeing my brother aggrieving himself, I feel heartbroken too..."
"So, what you mean is, my sister with your brother feels very aggrieved, huh?"
"Even if you speak to me in this tone, it can't change any fact."
