THIS IS REALLY NOT A DRAMA WORTH DROPPING. It has a great storyline and it is very mature. That is if you can't handle mature content (for the younger viewers and the few that just don't like those things) I say don't watch it because you have a higher chance of not liking it. It is honestly really worth the time and I hope that the next episodes live up to my expectations which they probably will.

Update: Finished the series (which I hadn't previously done when I wrote my review) and I... LOVE THE ENDING!!!
I won't lie, the ending definitely will leave some people unsatisfied as it does not give a definite answer on where the main couple stands but it does hint that they eventually end up together it's just that we don't see them as a couple in the drama. (but they do end up together lol just making that clear)

I enjoyed the struggles the main couple faced throughout the drama, to be honest. It makes it seem more worth it in the end. I honestly didn't like the cheating part, but it makes sense in the context of the drama. (in a way)

I would a 100% recommend and rewatch whenever I have the time.
