I already knew I loved this drama, but upon rewatching it I realize that this is truly one of my favourites. It's getting knocked down from being a perfect 10 because there are a few moments when the plot gets a bit too melo for me, but on the whole it's a minor quibble. This drama is wonderful.
Where to begin? I love the tone. It can be bitter and dark, but also hopeful and fun. I think that dramas like that get the closest to describing life how it really is. Even though it is heavier than the average romantic drama, it doesn't feel oppressively grim like it could have under different direction. The drama focuses on overcoming trauma, and all the suffering and joy that can come from that.
It's also interested in the real world -- I love how much is set in dockyards, back alleys, and on the construction site. This drama is so unglamorous. Its characters wear regular clothes and live in regular houses, and the leads are rough around the edges even at the end. I love when dramas that do this! There are so many dramas where everyone feels like they're living in some kind of dream world, whereas this feels so grounded and it makes me more invested.
The leads are also fantastic. There are few couples that I feel more passionately about than these two. They both feel like real people, and are flawed and three dimensional. I can understand why they fall in love because I was falling in love with both of them while watching! Their relationship is a real slow burn, but I think that makes it even more worthwhile. It builds over time in a really natural way and the obstacles they face and overcome feel earned. On top of all that, they have great chemistry and they have great conversations. I love how open and frank they are with each other.
Overall, what a great drama. So balanced, so heartfelt, so moving and so well paced. I feel like this makes me emotional in the same way Reply 1988 does -- I am so attached to the characters and their journey. I can't recommend it enough.
