I know there were much hype for this drama because it centered around Twitter and it had the famous JaeJoong starring in a Japanese drama. I think initally it started off well, but it just got disappointing after the first or second episode.
I personally feel like this was trying to follow Last Friends but totally backfired. Last Friends over this show anytime.. Unless you are a fan of JaeJoong or any of the others, than you might enjoy it more than I did.
