I'm almost speechless when it comes to this drama, that is how good it actually is. Usually i'm a fan of the romantic/comedy type but for some reason I watched this and oh WOW! It is just pure amazing. This show made me jump, scream, laugh and cry, my husband asked me if have turned nuts;). One second your thinking Is he a gangster? other your thinking OMG no he can't be, he must be undercover, then ooh no he is sooo bad and next OMG HE IS. It's not limited to the main leads but also to all of the supporting casts, they seemed all to be so very good planned out. Chemistry between all of them was really nice, the bro-chemistry, the family-chemistry and the love-chemistry. No sloppy violence. I'm sure i'm not alone thinking that its nice when a show ends in a realistic manner or unexpected. But some shows, you just wish they could end the way you want it, somehow Kdramas and especially this use the ending to make you keep thinking about the show over and over again after its done. I LOVE IT.. can't stop thinking about an alternative ending in my head. Im out of praises, watch it and you will love, it.
