Let's not talk about sympathy for now. If she ends up being the one to pass on this story, then even if she wants to get rid of this hassle, she might not be able to. And as soon as Mei Yinan gets angry about it, she'll remember who complained to her in the first place—which is Mei Mengzhen. Over time, how could Mei Yinan not start having negative feelings toward Mei Mengzhen?
Another thing: Mei Yinan feels bad for her brother, but no matter how much she pities him, there's always a bit of distance. So when it comes down to brother versus niece, how to weigh them in the end is a whole other matter. Anyway, at least Mei Mengying's issues will be managed by someone; as for what happens to her and Mei Yongfu, that's outside her jurisdiction now.
Honestly, this was a pretty masterful move.
