The two families were simply addled, what exactly where they supposed to do next? It was not exactly a proposal but a betrothal was probably the next best thing.
The women looked at the old master, as the patriarch, it was sort of in his department to handle the situation. The old master stepped in as expected.
"Uhm, in-laws," he said to the Chi's "as you can see Muyang has made up his mind. We as the adults support his decision so I have nothing much to say except that we cannot wait to officially welcome Chi-Chi into our family as our daughter." He concluded his words with a humble bow.
"Yes, in-laws," the old madam added, "We have been waiting for this moment for a long time. With a betrothal we can all be contented knowing fully well that their future together is certain. What Muyang has given, we are prepared to give more."
