Deciding to watch this drama on-going was the right decision. I started this drama because of THE Kim Hyeyoon and time travel is one of my favorite genres. The first ten minutes of the pilot episode managed to take me into a deep emotion when Im Sol lost her willing for life and then she got a glimmer of hope from Ryu Sunjae and it became the turn point of her life. Im Sol's life as a fangirl also makes me feel very familiar and relatable. The development of the story then made me feel like I was riding a roller coaster of emotions and the experience of watching this was like taking a trip to somewhere for the first time and I couldn't guess what they would give me next.

Time travel back to school plot and first love stories are nothing new in East Asian dramas and I have watched quite a lot of similar stories before. However, this drama is able to give me all new feelings that I have never felt before from the same genre. This drama succeeds in presenting elements of comedy and also romance very well. The romance was conveyed so beautifully and it succeeded in making my heart flutters so many times, while the comedy succeeded in making me laugh out loud. Other elements, such as angst and the mixture of various existing tropes, are also mixed well which makes this drama so rich with flavors.

The two main leads have very strong chemistry and each complements the other. Kim Hyeyoon is an actress with wide-range acting skill. She previously proved her ability in several roles. Here, she plays a quite complex role. From just one drama, she is able to convey various emotions in an extraordinary way. Kim Hyeyoon's strength in my opinion is that she can make her co-stars follow the same rhythm as her. Even though Byeon Wooseok is an actor who has previously shown his abilities in several roles, but perhaps this is his best role so far, especially in the romance genre. I also need to praise the director, because of his excellent works he's able to present Byeon Wooseok's microexpression so well. To play the main role in the romance genre, good synergy between the two main leads is very necessary. Kim Hyeyoon and Byeon Wooseok are a very matched couple that this drama successfully presents to the audience, so that we can feel what a romantic comedy should convey through the screen.

Cannot be avoided, in the time travel genre it is difficult to avoid plot holes, especially if the episode length is limited. Actually, I hope there are several things that are explained more in this drama, but I don't think this is crucial because this genre is fantasy romcom, not a sci-fi. For me, that is not a weakness of this drama, because the main message this drama wants to convey is already delivered.

When watching this drama on-going, I was very excited and also worried about the development of the plot, but thankfully until the latest episodes I was still able to really enjoy it, as I enjoyed it at the beginning. I am currently so grateful because I have found a good romcom drama again after a long time, but this also has a negative effect on me because after this it will be difficult to enjoy a similar genre for quite some time. Up until now, I have rewatched it for so many times, because rewatching this after the story develops further gives a stronger feeling.
