Honestly, I had a hard time deciding whether this drama is a masterpiece or not. Of course this drama is one of my ALL TIME FAVORITE. But not really the best. Maybe because this drama is just lots of fun (and tears) and I shouldn't care too much about some plot holes and missing answers. Before the last episode, we had lots of scenes involving wars inside company, chae yeon engangement with ki joon, the mom being so evil, and the grandma desperately sobbing for his son, and all of those constant flashback. But in the end, these screentimes didn't even seem too important. I just realized they were just dragging times, and taking away the slot for other more important scene. We should've had chance to see some interesting scene, like how Oh parents will react when they know Perry's real identity. How mom, and grandma will do with Do hyun-Ri Jin relationship. How will Jun Pyo live after 21 years of coma. And of course, some longer scene for personalities. Like perry park running away from SEUNGJIN office, went fishing with papa Oh, riding a REAL boat. But overall, the story is great, nicely wriitten, and makes us wanting more and more and more. I hate it when it ends. About the acting... Well I watched previous Ji Sung's works (save the last dance, PTB, my ps partner, secret), I knew he always did great potraying characters. This time he surpassed my expectation. Bows down. Other character also did a good job. HJE is really good with her expression. LOL. What I complained the most is not her screaming, but her choice of clothings. It bothers me a lot to see her wearing oversized top and trousers all the time. I wish Shin Segi was not only complaining about her make up. -_- AND THEIR CHEMISTRY, unfortunately is not as strong as what happen in drama Secret.The kiss was too plain compared to THAT CAR KISS AND THAT TABLE KISS, Secret fans must know what I mean. Maybe I am a sucker of melodrama, but I love them better in Secret. Sorry. :( I love drama that could make me laugh and cry with the characters, this drama is definitely giving me great laughing times, and wonderful crying times. This is the only drama that made a scene where a girl giving kiss to someone other than his boyfriend, so beautiful.
