This is a nice little movie you can watch whenever you're feeling down and are looking for something uncomplicated to watch. However do not expect much from it. Yet, Kim Go Eun and Jung Hae In did a great job and their characters' feeling get though just fine. The chemistry between the two of them is incredible.
Regarding the storyline, nothing interesting happens, the timeline is managed very poorly and the writer wanted to make a big deal of some things rather small. They complicated things between the leads just so that the movie can last 2 hours.
I have no interest in watching it again, even though I truly love these two actors.
