The first few episodes are trying to be a stupid rom-com where SKJ has a perm and buck teeth. They're cringey. You won't miss much if you go directly to epi 3 or 4. That's when a completely different series starts, and though flawed and uneven, it has moments of unforgettable brilliance.
This portrait of a relationship between two imperfect people is raw, frustrating, and sad--because that's what relationships are in real life. Seo Kang Joon gives a heartbreaking performance as a young man who gives his heart to a woman who is too depressed and damaged to completely receive it.
I can't say enough about how great an actor SKJ is. Korean actors are the greatest in the world and he is the best of the best. There is a scene where he keeps stalling the inevitable breakup by desperately looking for a coffee shop. As the shops close and turn their lights off one by one, it's a metaphor for the light of hope being turning off on the relationship.
SkJ manages to go through the stages of grief--denial, bargaining, and acceptance--without saying a word, all in the space of two minutes. It's all in those famous, wounded, amber-colored eyes. He has a rare soulfulness for one so young.
In the scene where his ex drunk-dials him, he doesn't say a word. The camera moves in on his face. He barely moves a muscle but with his eyes and the slightest of microexpressions, he shows how conflicted his character is. He doesn't want to be sucked back in to her drama, but knows resistance is futile. And you can see it in just a flicker of the eye and an infinitesimal movement of the mouth. That takes serious acting skills.
Esom is also incredible here. So many people condemn her character as selfish, but when you're depressed, you just don't have room for anyone else. You barely have energy for herself. Her depiction of grief and suicidal depression was spot-on. At the end, we see her healthy and looking to the future. To me, that's a happy ending.
This is about adult relationships in real life. They're flawed. They're confusing. They don't always make sense. And they're messy as hell. The ending is not fairytale. It's better than that. It shows two people who learned from the relationship and are moving on, not just in their lives, but from each other. They've grown up.
All in all, this a flawed drama and is not for everyone. But if you like great acting, it's worth it, especially from Seo Kang Jun.
