The lead actors are fantastic, but the story is not very well written. I watched the whole thing because Ja and First did a wonderful job with what they were given. Especially considering this was their first time as the main couple in a show. There are only a few acting "growing pains" here and there. Mostly they are very natural, heart-felt, and believable in the wide range of emotions they expressed. And the way they interact with each other is both comfortable and magnetic. Awesome chemistry.

Their group of friends and Ja's mother were also enjoyable in their roles.

The script and direction were frequently awkward. Dialogues didn't have a natural flow, or give-and-take between characters. The director seemed to want to show all the latent pauses in-between words or actions that the weakness of the script created. The story/plot required a lot of suspension of disbelief, especially from Ep 7 onward.

Emotionally, there was a whole lot of unnecessary angst, but it was "enjoyable" because of Ja and First's dynamic. In other words, it hurt just right ;)

So if you like experiencing both emotional highs (there's a lot of sweetness too) and lows that are mostly resolved, really hot chemistry and intimate scenes, and can suspend disbelief and logic to go with the flow and not get frustrated, then this is great to watch at least once.

Slight spoiler of the end: it ends well for Ja and First's characters. For me, that's what makes it worth going through the angst!
