Before I wrote this review, I had to rewatch episode 1 because I wasn't really sure what happened with those two at the first place?!

I started this series with hate, because my logic didn't agree what I saw on this series. How could you forgive someone who failed you? or even delaying you for your graduation? I did something terrible when my best friend took my book a month before final exam (when I was in college), I can't imagine what I would do If someone failed me on my test like sang-woo did.

But... at a leisurely pace I fell in love with this series. Especially when their feeling toward each other gradually improved in every episodes.
