Here's the thing, I can see why people like this drama, especially if it's a nostalgic thing for them. Unfortunately, watching it now more than ten years later with no sentimental feelings towards it, it really does not hold up. It comes across as janky and low budget and barely held together.
Okay, so I'm going to sound like a hater, but let me vent here for a moment. I really hated the FL and ML. They both had the personality of mayonnaise and were about as interesting (more so in the case of the ML, who was not a very good actor). Due to this, I actually skipped most of their scenes, which surprise surprise is almost the whole drama.
But on that note, I weirdly really liked Song Joonki's character. He's not an actor that I typically enjoy, but he was really great in this drama and I finally understood why people liked him. He was probably the strongest actor here (sorry Yoo Ah In, I love you, but this is early days for you and you clearly hadn't reached your final form yet). Yoo Ah In, while not as strong as Song Joonki, was still good too and I really only watched both of their scenes throughout the drama.
I'm definitely hating on this a lot, but I did finish it because it does have that "something" that a lot of the classic kdramas have.
