I know this chapter is focused on Mugi-chan, but to see Kogane think back on the danger she and Goro faced is the highlight for me. She's moving away from just wanting to be married and focusing more on the time she and Goro have together and how uncertain it is.
As reasonable as Goro's hesitance is, Kogane's eagerness now also reasonable. They can now (hopefully) talk to each other about their relationship as a serious thing and not some fantastic fox bride scenario.
