I literally finished this Kdrama one minute ago and I'm here to tell everyone to drop everything what you are doing this moment and watch this drama! You won't regret it.

I start with the storyline. This isn't the story of a cute couple who falls in love with each other and ends up never leaving one another. This is the story of a couple not wanting to be a couple anymore. You probably heard of the cliche that every good romance movie/series/drama ends with marriage or having a child or just ending up together. And this is exactly what this drama critizises. Who said life will be beautiful and without hardships after marriage? Guys, this drama is about reality (obviously not because it's called "Go back couple" and you should know that you can't go back in time). This drama tells a story about regrets and youth but at the same time about hurtful but beautiful memories and adulthood.

Okay enough with the sweet talk. You want something to laugh? Watch this drama. You love references to other dramas? Watch this drama. You don't want the typical story of falling in love but rather learning to love again? Watch this drama. You want to cry your soul out of your eyes? Watch this drama.
I hope that were enough reasons and if not watch this drama and tell me more because I honestly don't see a reason to not watch this drama.
Enough about the plot and what this is about because you should have already read the story summary.

The story is about youth and adulthood at the same time and the cast still did such an amazing job! Nearly every role was present in past and future and every single character in this drama looked so natural. Even though it kind of seemed like they didn't age (obviously) they had complete different personalities but still so much in common with their past self. Maybe this doesn't make sense at the moment but you will realize it as soon as you watch it (why are you still here anyway? Go watch it!).

Okay don't let me start with the OSTs. My poor poor heart. Why would someone be this cruel? I had enough reason to cry because of the sad reasons every character acted the way he did but no, destroy my heart with the sad soundtracks why not. Anyway if you're not new in the kdrama world there will be some OSTs that will remind you of something ;)
To sum this all up I'm going to say one last thing: the first half of this drama was funny and enjoyable with cute and heartbreaking moments, but the second half oh lets not talk about that. That was just hurtful. I've never seen more realistic choices of fictional characters then in this drama. Everything made sense and because it was this realistic it made me realise that realitiy is cruel. The world we live in is cruel. That's what this drama is about. Beautiful life? Not exactly, more like painful reality smashed infront of your salad.
Please watch this drama, you won't regret it because this tells a real story.
And if you still don't see why you should watch this one last but most important reason: There is this super cute baby that is literally the reason for all pain and for all happiness that exists in this world. That child is reason enough to watch this drama.
Now go!
