It's not that bad but its not particulary good...I have no idea why it was such a sensation. It had a lot of flaws.
The main guy is handsome but theres really not a lot going on in this drama. I see some people mention there isn't a lot to SHG's acting and I agree. Some parts I really enjoyed but overall I was not that impressed. It was ok though. Totally overhyped and dragged on at times. I would only recommend to watch if you are bored and need to pass the time. There are better dramas out there.
