I have mixed feelings about this chapter. I'll admit that it gave a bit more time to address their relationship problems than I was expecting (which, admittedly, isn't saying much), but it was still a bit rushed, with them immediately accepting each other's apologies without talking things over.
At the risk of opening another can of worms, they didn't discuss what happened in Chapter 167 and whether it was consensual. Disregarding the debates about the severity of Mitsuki's actions, both of them clearly are thinking about that night in Chapter 168 and 169, so the issue hasn't been resolved.
