Do they not feel awkward?
Qin Mo almost became their daughter-in-law, and now even after things have soured, they still want to go. Ji Family, however, sees this as a great stepping stone, as it is through Chu Family's connections, and the guests are either rich or noble. If they could exchange a few words, it would certainly make future endeavors easier.
Who wouldn't want to go where there's potential for fame and profit?
"I am so furious, Qin Mo ruined my birthday last time. Why does she get to have a grand celebration?"
"What's the use of being angry! In the end, she's now close with Chu Yiqin and can throw her weight around. If you don't want to go, just don't. But if you go, don't clash with Qin Mo, or I won't deal with it."
Shu Yun was having second thoughts now.
