SPOILER ALERT!!! Considering that I hate romantic Kdramas--especially high school love dramas, this wasn't bad for the first half of the show. Yes, there are a lot of cliches...like a lot (love triangle, rich ML/FL, kidnapping, etc.) but it worked for a bit. Until it didn't. The plot that the FL kept going back to the past to change the future and the ML falling in love with her again every time just got old after 2-3 times. I found myself having to skip through a lot of the final episodes, which is something I wouldn't want to do since shouldn't the last episodes be the best parts? Regarding the side stories to this show, I felt like a lot of it was left unanswered/unsatisfying. We never got to see what happened to the 2nd male love interest, the motive of the killer, and her brother's relationship. Idk maybe if the director allocated more time to the side story, it would've felt more complete.
