I found this by accident and even if it's a bit outdated I decided to try it anyway.
I liked the fact that the main lead was not the always present dick of a chaebol but a normal guy, yes he's not poor but he's not the top of the top of the top and so I didn't had to watch any of those cringeworthy scenes of him choosing between a several amount of clothes , cars and whatever. So no "wealth bragging" and his character was quite cute, I can even understand why for a while he was confused between Chae Rin and the female lead, I mean she loved that noona for so long and she didn't see like us her true face..so the male lead, considering this is from 2005 was cute and I happily cheered for him!
The fem lead was okay I guess but she was kind of annoying in the middle, they both made clear they feelings for each other but they were going slowly because she was reluctant to go for it.
The supporting characters I loved were the father in law (cuteness run within that family lol) and the male classmate, he had the right intuitions and gave the best advices (at the very beginning I thought he was going to be a love rival, fortunately he had only eyes for Dan Hee), also I can understand why at some point Dan Hee pushed Chun Yang towards the awful ceo, she was trying to protect her from the sufference caused by Myong Ryong's wavering.
The second leads just made drop the value of this drama, but you know, without them the show would be ended by the 4th episode xD
The things that made me despise them are two: the motivations for keep chasing the main couple were based solely on pride and jealousy and not love but most of all they were always in the right place at the right moment eavesdropping some important infos (like where the main couple is or what are their intentions)...at some point I exclaimed a "come on" so loud because of this that I scared my husband xD
Oh another annoying thing: the opening with all that screaming and noises. (????)?????
