I watched this for mainly 2 reasons: 1. Park Seo Joon 2. Everyone kept saying how great this show was.

And not gonna lie. It IS great.

It keeps you hooked to the end. However, it seems to have very high standards as a kdrama, but the last two episodes were kinda... what? NO SPOILERS, but some things that happen in the last 2 episodes are a bit... unrealistic and weirdly plotted.

But the ending is great, so if you're unsure on whether to watch it, I'd say watch it and judge for yourself!
