Amazing, 100/10. I haven't finished it yet, but that's only because I was watching it too fast and wanted to take a short break. Trust me, when I finish what I'm currently watching, I'm for sure going back to finish this. It is just too good! Plus, she can handle her own shit, I love a female lead who actually leads. Chef's kiss.
P.S. It is longggggg, but that's normal for C-dramas, and the plot is totally worth it, trust me. I was irritated by how long it took her to figure out his secret, but the plot was still plotting!
