It's a nice movie. The chemistry between the main leads was there as for the acting part I loved Jung Hae In's acting (as always) from the start till the finale as for Kim Go Eun's it was good but not as good as I expected a few parts felt like they needed more work, that's why I'm giving the 8.5 at the Acting/Cast rating...
The music playlists was quite good.
I think the story/plot was good but with a little better editing in the time jumps and maybe with some more information that they could give, it could've been better...
So, it's not a movie that I will come back to because of the story, but I'm gonna come back because of the filings that leaves you with..and let me be honest I'll come back because of Jung Hae In too of course ..
