If you like Gong Yoo's acting and are looking for something to fill time, this is that drama. But, I can't say though I would ever watch this again. See, I tried really hard to like this drama, I really did, but I just couldn't. Despite having Gong Yoo as the male main lead, the acting really lacked and was confusing to understand. The plot itself was this drama's weakest link. Seen with family relationships that border on incest, odd plot holes, reconcilations that should never happen in reall life, a poorly executed "I'm dying love me" storyline that was thrown out the window near the end, and the never knowing Gong Yoo's character's true intentions till the end made this drama VERY hard to watch.
Again I'd like to empazise the added sibling-esque relationships at times made this drama really uncomfortable to watch so, be weary of that. The OST was okay, nothing to write home about. To sum up if your bored, sure go ahead and watch this drama.
