Despite the title, I did enjoy this drama, I really did. I've had my doubts, throughout the course of my watch, mostly because of a few writing decisions, but I ended up liking it in the end. However, based on other people's perception of the drama, I don't think it's that good, as many people say it, some say that it is the drama of the year, which is a WILD statement, but then again, I feel like the dramas this year a bit lacking, so who knows. So let's go over this. I did enjoy the story, I was a bit vary at first when I learned that it is a time travel drama, It's not like I dislike them, but they tend to yolo some of the story elements quite often, and I also did see that here aswell unfortunately, but far less than what I am used to which is a good sign. I enjoyed the interactions, between the leads, and seeing their relationships develop, I especially loved the fact that this wasn't a fan and star story, but rather than a story about friends turned lovers, and I especially loved seeing both Pov's, because it made it even more wholesome. The time travel aspect of the story was a bit inconsistent, especially when it came to the rules of what our female lead could reveal to others in the past especially when the plot found it convenient, I was like, "WHERE DID THE TIME TRAVEL RULE GO?" The one thing I hated the most about the plot was the antagonist, if we can even call him that. It felt like he was a plot device, rather than a character, because we literally knew nothing about him except that he was a serial killer, we didn't even knew why he was obsessed with Im Sol and Sun Jae, so throughout my watch I looked as him as a plot device rather than a character. I also did enjoy the fact that the story jumped through different timelines, and time loops, it made things fresh, though towards the end, I felt like it was a bit overdone and got repetetive. There was also a love triangle, which thankfully wasn't the point at all, and had little significance. I also liked the fact that they made the ML engage with the time travel idea, I think they could've and should've done more with this, but I'm just glad they included this, because frankly, I wish more time travel dramas would. I also enjoyed the ending, I think it was a fitting one for the characters. I had a bit of a problem with the acting however, I found the female leads's acting especially cringe at times, and especially her brother and best friend, sometimes I hated when they were on screen. The one thing I loved the most about this drama was the OST, it was so freaking beautiful, and gave such a beautiful aesthetic to the scenes, and I found myself singing along sometimes, which was funny to see. Overall even though I enjoyed this drama, I really wouldn't say that it's the best one this year has to offer, but I still think you should watch it if you like the time travel concept (and don't mind the plot being messy sometimes), with a good romance.
