It started off really great and had a lot of humor, but, for me, became very predictable, dragging, and annoying for the majority of the scenes not long after. I applaud Gong Yoo for his acting; his crying scenes are heartbreaking. Yoo and the minor characters, GDR's parents, brother, the parents envious past "lovers," and the teachers are what I looked forward to watch. Shin Won Ho is a great young actor, and what a waste that he had to play sleeping beauty for the majority of the drama. I would had preferred if they mixed him in every now and then like in 49 Days. And Yoo's original character, SYJ, wasn't much of character. For the audience, we barely know anything about him--whether he's bad, good, a cheater, and etc. So right away, KKJ is likable because of a very misjudged and very vague antagonist. The heroine is the worse. She's naive, pitiful, and annoying. She lectures KKJ all the time about being an adult, when she acts worse than a teenager. I found KKJ the adult in this drama. GDR kept being easily persuaded by Ma Ri all the time; she never listened to her gut or defended her man. Kudos to Lee Ming Jung for playing such a horrid heroine so well. Ma Ri's character is annoying, manipulative, and clingy--but what do you expect from a spoiled teenage girl that has been in love with someone, I assume for years? Another waste of a character was SYJ's other "love" interest Lee Se Young played by Jang Hee Jin. Ma Ri's character completely overshadowed the potential LSY character's had to play an evil antagonist. Overall, I might not know how it ends yet, but this drama lacks in so many aspects that no matter the ending, it won't woo me now. I'm happy I began watching it because it introduced me to Gong Yoo; I'll check our his other works in the future.
