It's hard to put it into words, but this drama was frustrating. It was a nice story...but not really? It had potential, but it turned out messy. The device concept was weird and didn't make sense to me. It was so creepy that he was obsessed with her for 10 years. Mone on dude. Have some self-respect. Something was off about his character. I felt like I didn't know him and didn't understand how his mind workes.

I didn't like that Seo Woo kept using the device when she barely knew Seo Jin and lashed on her Seo Jin's husband. Like she has any right to use that device. She was really nosy and it was weird that they bonded over a device. I couldn't take them seriøsuly haha. Their conversations at the beginning were really weird too...when she told Ha Won, a stranger at the time all about Seo Jin and that "mysterious" man. I didn't like how she wanted to keep the letter from Ha Won. The other characters. i didn't feel like I could connect with them. They were just "there" Moon Soon Ho was really annoying. Ji Soo was boring and overdramatic. I loved the main leads' relationship. It was slow and fun to watch Ha Won fall in love with her. The hugged too much though... OST was really good. It fit perfectly. This drama was weird...? And a bit all over the place. I already predicted the "secret" It was boring at the beginning then it got better when the focus was on the main leads and then boring again. I had a hard time finishing this.

I felt like this drama was easy...not many things happened. Sometimes, I felt like i kept seeing the same scenes all over again. There were way too many flashbacks where it wasn't needed. I skipped them all and I also skipped a lot of scenes with the supporting characters. It's just visually beautiful -The scenery was amazing, the thoughts, quotes, and reflections on life but if you look closely at the drama you can see that it was bland and tried too hard. I felt it could've addressed mental health better. They should've filmed in other places too. I wish we got to see more about Ha Won's work as a scientist. I'm a bit disappointed in Jung Hae In for taking this role. He can do better:( I'm from Norway and they pronounced the words wrong. Even "OSLO", but that's not important haha
