I have waited to watch this for about 3 months. During the last month I was constantly searching for it every day just to see if it was out. And when I finally found it u can't believe how exited I was.!! >_< YeoJinGoo who's only 16 irl and playing the character of HwaYi was amazing. He has many scenes and the story was overall about him. His acting and performance was spectacular. The upbringing he had in this "family" containing 5 fathers and a women who was taking care of him. The things he had to go through and how it affected him. Him still being so soft and sane inside while hurting. Him laughing, crying, hurting, fighting and getting furious. The look in his eyes when he realized everything. OMG. I bet he's getting an award for this. Korea is all over him saying he's gonna be THE next TOP actor. Seriously the guy is only 16 but looks around 20. I can't believe I'am saying this but I LOVE HIM. He's smoking HOOOTTT and 4 years younger than me. His voice is so mature and sexy…. ahhh I'am boiling. xD Every one of them deserves an award. The actors playing the father were great at their roles. They had me hooked on the spot.!! The storyline was amazing. The concept of the monster and the symbolic meaning behind it was very well-thought. I looooveeed the action, fighting and car scenes. It was just perfect. I loved the pace of the story too. There wasn't a single moment I was bored. Warning: It contains a lot of blood-splatter so it aint for the REALLY weak-minded. But if I was u I would watch it. It's a must watch. Goes right to my top 5. ENJOY :D
