I haven't seen the two other versions so I'm not really in the position to make any comparison, so I'll just write this review based on the criteria. Story is okay, it's not original of course, since it's just a remake, but I did like how the story progressed. The pacing was just right, not too fast nor too slow. I loved the side stories better though than the main plot itself. The cast was lovely, but the lead couple's acting was so-so. I'm a Shawol, but I kinda find Minho's acting annoying at times. Sulli was bearable for me though. This is the first time I got more interested with the supporting characters rather than the lead couple. The supporting characters had more substance in them. I'd especially like to commend Lee Hyun Woo. That kid really really really really really knows how to act. It was him who carried the entire show, in my opinion. He knows how to be cute when he needs to be cute, and knows how to be sad when needed. He can portray well whatever he needs to portray, and I was really awed by his great talent at such a young age as that. Honestly, I don't think I'd manage to finish this drama if not for Hyun Woo's adorableness. The music was great. Well it's really no surprise since the production company's SM entertainment and it'd be really disappointing if the music turned out to be bad. Overall, the drama's only visually attractive, but not so substantial, so if you're looking for something pretty to look at then you could try this one out.
