A really cute rom-com with predictable villains. This is a classic case of rich boy falls in love with poor girl (but think she's a rich girl). If they tightened the storyline and made it 12 episodes instead of 16, the story would be even better. Last few episodes could be scrapped altogether as they didn't add much to the storyline. Otherwise, the plot moved forward at a reasonable pace. Acting between the leads was serviceable. Yang Jin Sung's acting as the doppelganger is decent. A lot of times what happens with an actor playing two roles is that one role often is more fleshed out than the other, while the other one is often more serious and emotionless. The same thing happens here so I wasn't blown away by her acting. I don't know what the ages for the actors were supposed to depict in the drama but both leads acted as if they were in their early 20s. Made me believe there is a romance, albeit more of an innocent first love kind of love rather than one that is worth risking your all for. Use of the music was effective for this drama. Overall, not bad for a rewatch, as it was one for me!
