I feel like the dynamic I most expect to see between Luo Binghe and Shang Qinghua is LBH begrudgingly accepting that SQH's presence is necessary as Shizun enrichment.

That being said, I always love when a fic's cast is basically a binqiu+moshang double date as they deal with whatever the plot throws at them. It's like some kinda fucked up in-law family kind of deal, but it works for them.
