I don't understand why a person of 28/29 years old who regrets her life decisions would keep acting as a 19 years old teenager when she is given another chance of redoing her choices. In fact, it's pretty easy to understand why she failed first time by just watching the two first episodes. And I don't know the reason why a paralegal with many years of experience working for a competent lawyer and big firm would act as a completely amateur. I think the scriptwriter forgot she has come back from 10 years in the future and she's not a teenager anymore. Because if she was going to act reckless and without a serious self reflection, this drama already failed for me. If the scriptwriter is waiting for give us that later, so the timing is wrong. I saw 5 episodes and she seems to be satisfied with using what she knows from the future or using the ML to get a better place in this life, and it makes she to be totally unlikable for me, because she didn't want a chance, she wanted to all be given to her. And the ML gives it all to her, but she can't tell it. So I could not continue to watch more. I feel sorry for the actor who plays the ML, because we can see that he did the best he could... But the actress over infantilized her character who was already immature... But I don't think the result would be different because the script miss the main point. It's not about a teenager growing up into an adult. It's an adult in a teenager body trying to make the right choices that her teenager version couldn't do. She should have "character development", but with the right starting point. The ML also seems to be the same during those 10 years too... he's the type of a mature guy with cold facade and warm heart. But nothing sounds good enough to keep me watching it.
