I watched these series after watching SWEET REVENGE 2 and they were really cute. I really liked it. The story of the drama was really cute and it was a good one too. The acting of the actors was good too. JI MIN HYUK was looking really good in the drama and he really pulled off the character of the robot pretty well. The lead actress was really beautiful and her acting was cute too. The rest of the cast was good too. But I was a little disappointed with the ending of the drama. The ending starting to sadden me as he ( DO YOUNG ) wasn't allowed to meet GA EUN but he comes back in the last. So, it was a happy ending after all but I was confused that how was he able to come as he had two options : to stay with her with erased memory or away from her with her memories that's why. But overall, it was a good drama so I recommend it.
