Well well well.... 6 episodes have aired already but nothing important has happened yet. The plot is too common and slow paced. The acting is not that good either.

Is it boring? Yes
Is the main female lead annoying? Very
Can we expect the future episodes to be better? Ummmmm......I don't think so. No.
Is it worth the watch? No
Am I gonna drop it? Yes

Just watch it if you're a fan of Choi Tae Joon (can't give you more reasons to watch it other than that).
Oh! and if you're a fan of the female lead (Choi Soo Young) go watch 'Tell Me What You Saw' (100% worth the watch).
