What I learned from all this is that it's easier to have a relationship with an alien than with a North Korean.

I also learned the importance of money and being born in an important family.

It took me a while to watch this drama because of the hype around it. I kept watching spoilers and I was worried they'd ruin the experience for me. I was wrong. The story did that on its own.
Yes, my expectations were high since I loved this author's past work. The drama wasn't bad, it just wasn't as good as I thought and it makes it very hard for me to understand all the hype around this drama.

The main thing that still sticks out for me is that Yoon Se Ri is not a likable character. She's not relatable, she comes from privilege and meanness and that makes all the acts of kindness she does seem unauthentic. Even at the end. How is it believable that the CEO of a major corporation spends her lunch hour with her subordinates in subway? They could have least set the lunch up in their meeting room or in the company's cafeteria. I know, I know, product placement and all.

There was no chemistry. I don't know if the main actors were compensating because of the dating rumours but there was no chemistry. The sweet moments were very few. You mean to tell me they meet each other for the first time after being apart and all they do is eat, work, shop for clothes and work and exchange couple rings? There are no demonstrations of love and this is why the very dramatic scenes seem a little artificial, because there was no proper build up.

The secondary story was done better but there was absolutely no reason to kill him off. The scene was dramatic enough. It was just cruel and I didn't even care for that character that much.

There's a difference between being uninformed and being dumb. There was no need to depict North Koreans as dumb. They even did that with the main character. He lived alone in Switzerland, I'm sure he would know how to use a coffee machine or would at least figure it out. I'm not going to talk much about how they depicted North Korea because I don't have enough information, it seemed as if they went with a 70's theme as that's it.

I did have some fun, I did enjoy the story and had some laughs and cried a little bit as well.

The ending is very bittersweet. They misused the fingerprint door thingie. It would have been more impactful if he showed up at her place at some point. Their encounter was a bit anticlimactic.
They spend two weeks together every year. I have a closer relationship with my mail delivery person. Even the alien from another star was able to come back and have a proper relationship. The mermaid had to stay near the ocean but she was present! Why didn't they both move to Switzerland or any other country? He lived abroad before.

Anyway, I'll miss some of the characters.
