Oh wow I'm honestly a bit surprised by seeing some people that didn't like this chapter, and are done with the series, but too each their own.
I for one love just seeing various parts of their relationship, and their life together now. It helps strengthen their bond, I don't need constant things going on, like drama and so fourth, I simply get joy from seeing how much these two love each other, and have opened more in general because of their relationship. Plus the whole waking up together, warming up, snuggling on the train, getting to see the first sunrise of the year and happy that they're together. I genuinely loved this chapter, and the relationship these two have built up together.
