I had high expectations for this drama, since it's a very popular and well known. This drama completely failed to interest me. The story line itself isn't something unique; rich boy fall for poor girl. At first I found it very interesting and loved JanDi's personality but It changed too quickly after a few episodes.Meaning that her personality did a complete flip, yes i understand this is a romance drama and usually their personality softens but for the story to seem more realistic i felt that a part of her old self should've been seen. The only reason i managed to finish it was for the side characters. The Side characters' personalities were stable and acting were superb and felt myself rooting for the them opposed to the main couple. The main character couple just got repetitive and made me lose interest quickly.Honestly I felt it was due to the duration of the drama. The acting was superb..I've seen dramas with Lee minho and Goo Hye since they're very popular, but this drama, in my opinion didn't make me fall in love with them like their other dramas did.I'm not sure if it was due to their character or not.I will admit their acting seemed very natural and since I've seen them in other present dramas I can definitely say they grew as actors with the experience. Music was entertaining I enjoyed the majority of the songs. Mainly the ones from SS501 and SHINee. Felt everything matched very well the climax of the story till the ending. The F4 aka the popular rich guys are everyone's dream boy, they're the perfect representation for the ideal men.Which is why till this day most shows in korea used them as a reference when describing a group of good looking men.This drama is constantly looked back which is why it's famously known. I will not be re watching this I know that for sure. Unless you really enjoy a over dramatic love stories then I don't recommend this drama. All actors and actresses portrayed their characters well but the overly storying line and duration made the overly experience fairly poor.
