It's a semi slow-paced drama that slowly builds up throughout the story. There's nothing special in the story; it's a common story in a way, but I really don't mind watching drama with the same themes or similar stories as long as it holds my interest. There's something the main leads both struggle with and they both end up having a connection with each other. I thought the drama was predictable with some parts with all the flashbacks they were revealing in the start, but they did throw me off and I turned out to be wrong so at least that part was not boring. They did a good job of resolving the main leads conflicts and tying up the story together without leaving any major mysteries behind. A part of this drama seems to also lowkey shed light onto the lives of Korean celebrities in a way and how the media goes crazy regarding them and their personal lives. The romance between the main leads was very sweet and not cringe surprisingly. I found them very adorable in their scenes together. The slow pace didn't seem to bother me till the very end where most things were wrapping up and I wished they would tie things in together quickly.

Music- There were two OST's that stood out to me and I liked. It was Jooyoung's "Here We Are" & Yangpa's "A Memory in My Heart".

Rewatch&Overall Rating- I wouldn't rewatch this since I personally don't find it enjoyable to watch again since I already know what happens throughout the drama and the suspense wouldn't be there anymore. That's one of the reasons I gave it a 8.5/10 . Another reason was I was tired of seeing the same flashbacks over again. I realize that they want to show that the guy has hyperthymesia and he's recalling a memory from the past, but it was getting a bit on my nerves to have to see the same flashback more than three times.
This drama is nice to watch with a nice ending but I wasn't really attached to this drama or its character enough to be able to rewatch this.
