While many Kdrama's focus on the process of falling in love and the struggle how to become a a couple and all the tension coming with it, that drama deals with the burden and obstacles that come up when you don't see everything through the rose-coloured glasses any more, become a couple, marry,...

So stress at work, loss of a relative, lack of time, growing old and getting a long with it will be something everybody has do deal with at some point and when everything becomes to much and none of the partners can escape from the vicious circle it can end up how it ended up here in the beginning. And while raising a child will give you a wonderful experience it's also a huge task to fulfill and to fulfill it especially to the level you want it to be fulfilled. All of that is kind of addressed in the show in some aspects more or less.

Though of course in real life nobody can go back in time and do like the FL/ML but that's what this drama in the end is there fore. It makes you clearly reflect on your own behaviour in the past and how sometimes things just get out of hand and in the wrong direction. It teaches us to reflect on our own, to talk more and take more care of each other, not only in a relationship sense also in general and that's what makes this drama so valuable.

It's also covered very well how the FL and ML deal with their previous crushes in their university time. The special story between the FL and her mother is addressed in a very heartwarming way and of course how the FL and ML missing her child.

The music is quite memorable, when it comes to that melodramatic piano tune. I'd say it's also a good rewatch value for some scenes. My only complaint is that the ending and resolving is a bit rushed and bit to easy, as normal life won't be like that, but you can say it's something to look forward to, of course. And in some scenes you really want to smack the ML for how he's talking/baving to the FL.
