If you have watched the other episodes i would say watch this. its a rounds out the season decently and the ending is cute.
However it does make me wish harder for a 2nd season just so we can see their lives during the early stages of their small family.
This is one of the special episodes i would say is more of a feeler to see if their is a audience for a 2nd season I would say but it n makes me wonder about the other couples in the show proper like how do they have kids? have they all married? how their careers are going? so many questions
